Module:

ExchangePowerShell

Applies to:

Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online, Exchange Online Protection

This cmdlet is available in on-premises Exchange and in the cloud-based service. Some parameters and settings may be exclusive to one environment or the other.

Use the Set-MailUser cmdlet to modify mail users. Mail users (also known as mail-enabled users) have email addresses and accounts in the Exchange organization, but they don't have Exchange mailboxes.

For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.

Description

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.

Examples

Example 1

Set-MailUser -Identity "John Woods" -ExternalEmailAddress john@tailspintoys.com

This example modifies the external email address for the mail user named John Woods. Note that the original external email address isn't kept as a proxy address.

Parameters

-AcceptMessagesOnlyFrom

The AcceptMessagesOnlyFrom parameter specifies who is allowed to send messages to this recipient. Messages from other senders are rejected.

Valid values for this parameter are individual senders in your organization (mailboxes, mail users, and mail contacts). You can use any value that uniquely identifies the sender. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Email address
• GUID

You can enter multiple senders separated by commas. To overwrite any existing entries, use the following syntax: Sender1,Sender2,...SenderN. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Sender1","Sender2",..."SenderN".

To add or remove senders without affecting other existing entries, use the following syntax: @{Add="Sender1","Sender2"...; Remove="Sender3","Sender4"...}.

The senders you specify for this parameter are automatically copied to the AcceptMessagesOnlyFromSendersOrMembers property. Therefore, you can't use the AcceptMessagesOnlyFrom and AcceptMessagesOnlyFromSendersOrMembers parameters in the same command.

By default, this parameter is blank ($null), which allows this recipient to accept messages from all senders.

Type:	MultiValuedProperty
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online, Exchange Online Protection

-AcceptMessagesOnlyFromDLMembers

The AcceptMessagesOnlyFromDLMembers parameter specifies who is allowed to send messages to this recipient. Messages from other senders are rejected.

Valid values for this parameter are groups in your organization (distribution groups, mail-enabled security groups, and dynamic distribution groups). Specifying a group means all members of the group are allowed to send messages to this recipient. You can use any value that uniquely identifies the group. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Email address
• GUID

You can enter multiple groups separated by commas. To overwrite any existing entries, use the following syntax: Group1,Group2,...GroupN. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Group1","Group2",..."GroupN".

To add or remove groups without affecting other existing entries, use the following syntax: @{Add="Group1","Group2"...; Remove="Group3","Group4"...}.

The groups you specify for this parameter are automatically copied to the AcceptMessagesOnlyFromSendersOrMembers property. Therefore, you can't use the AcceptMessagesOnlyFromDLMembers and AcceptMessagesOnlyFromSendersOrMembers parameters in the same command.

By default, this parameter is blank ($null), which allows this recipient to accept messages from all groups.

Type:	MultiValuedProperty
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online, Exchange Online Protection

-AcceptMessagesOnlyFromSendersOrMembers

The AcceptMessagesOnlyFromSendersOrMembers parameter specifies who is allowed to send messages to this recipient. Messages from other senders are rejected.

Valid values for this parameter are individual senders and groups in your organization. Individual senders are mailboxes, mail users, and mail contacts. Groups are distribution groups, mail-enabled security groups, and dynamic distribution groups. Specifying a group means all members of the group are allowed to send messages to this recipient.

To specify senders for this parameter, you can use any value that uniquely identifies the sender. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Email address
• GUID

You can enter multiple senders separated by commas. To overwrite any existing entries, use the following syntax: Sender1,Sender2,...SenderN. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Sender1","Sender2",..."SenderN".

To add or remove individual senders or groups without affecting other existing entries, use the AcceptMessagesOnlyFrom and AcceptMessageOnlyFromDLMembers parameters.

The individual senders and groups you specify for this parameter are automatically copied to the AcceptMessagesOnlyFrom and AcceptMessagesOnlyFromDLMembers properties, respectively. Therefore, you can't use the AcceptMessagesOnlyFromSendersOrMembers parameter and the AcceptMessagesOnlyFrom or AcceptMessagesOnlyFromDLMembers parameters in the same command.

By default, this parameter is blank ($null), which allows this recipient to accept messages from all senders.

Type:	MultiValuedProperty
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online, Exchange Online Protection

-Alias

The Alias parameter specifies the Exchange alias (also known as the mail nickname) for the recipient. This value identifies the recipient as a mail-enabled object, and shouldn't be confused with multiple email addresses for the same recipient (also known as proxy addresses). A recipient can have only one Alias value. The maximum length is 64 characters.

The Alias value can contain letters, numbers and the following characters:

• !, #, %, *, +, -, /, =, ?, ^, _, and ~.
• $, &, ', `, {, }, and | need to be escaped (for example -Alias what`'snew) or the entire value enclosed in single quotation marks (for example, -Alias 'what'snew'). The & character is not supported in the Alias value for Microsoft Entra Connect synchronization.
• Periods (.) must be surrounded by other valid characters (for example, help.desk).
• Unicode characters U+00A1 to U+00FF.

When you create a recipient without specifying an email address, the Alias value you specify is used to generate the primary email address (alias@domain). Supported Unicode characters are mapped to best-fit US-ASCII text characters. For example, U+00F6 (ö) is changed to oe in the primary email address.

If you don't use the Alias parameter when you create a recipient, the value of a different required parameter is used for the Alias property value:

• Recipients with user accounts (for example, user mailboxes, and mail users): The left side of the MicrosoftOnlineServicesID or UserPrincipalName parameter is used. For example, helpdesk@contoso.onmicrosoft.com results in the Alias property value helpdesk.
• Recipients without user accounts (for example, room mailboxes, mail contacts, and distribution groups): The value of the Name parameter is used. Spaces are removed and unsupported characters are converted to question marks (?).

If you modify the Alias value of an existing recipient, the primary email address is automatically updated only in environments where the recipient is subject to email address policies (the EmailAddressPolicyEnabled property is True for the recipient).

The Alias parameter never generates or updates the primary email address of a mail contact or a mail user.

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online, Exchange Online Protection

-ArbitrationMailbox

This parameter is available only in on-premises Exchange.

The ArbitrationMailbox parameter specifies the arbitration mailbox that's used to manage the moderation process for this recipient. You can use any value that uniquely identifies the arbitration mailbox. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Domain\Username
• Email address
• GUID
• LegacyExchangeDN
• SamAccountName
• User ID or user principal name (UPN)

Type:	MailboxIdParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-ArchiveGuid

This parameter is reserved for internal Microsoft use.

Type:	Guid
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online, Exchange Online Protection

-ArchiveName

This parameter is available only in on-premises Exchange.

This parameter is reserved for internal Microsoft use.

Type:	MultiValuedProperty
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-BypassModerationFromSendersOrMembers

The BypassModerationFromSendersOrMembers parameter specifies who is allowed to send messages to this moderated recipient without approval from a moderator. Valid values for this parameter are individual senders and groups in your organization. Specifying a group means all members of the group are allowed to send messages to this recipient without approval from a moderator.

To specify senders for this parameter, you can use any value that uniquely identifies the sender. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Email address
• GUID

To enter multiple senders and overwrite any existing entries, use the following syntax: Sender1,Sender2,...SenderN. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Sender1","Sender2",..."SenderN".

To add or remove one or more senders without affecting any existing entries, use the following syntax: @{Add="Sender1","Sender2"...; Remove="Sender3","Sender4"...}.

This parameter is meaningful only when moderation is enabled for the recipient. By default, this parameter is blank ($null), which means messages from all senders other than the designated moderators are moderated. When a moderator sends a message to this recipient, the message is isn't moderated. In other words, you don't need to use this parameter to include the moderators.

Type:	MultiValuedProperty
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online, Exchange Online Protection

-Confirm

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

• Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.
• Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online, Exchange Online Protection

-CreateDTMFMap

This parameter is available only in on-premises Exchange.

The CreateDTMFMap parameter specifies whether to create a dual-tone multiple-frequency (DTMF) map for the recipient. This allows the recipient to be identified by using a telephone keypad in Unified Messaging (UM) environments. Valid values are:

• $true: A DTMF map is created for the recipient. This is the default value.
• $false: A DTMF map isn't created for the recipient.

Valid syntax for this parameter is "Type:EmailAddress1","Type:EmailAddress2",..."Type:EmailAddressN". The optional Type value specifies the type of email address. Examples of valid values include:

• SMTP: The primary SMTP address. You can use this value only once in a command.
• smtp: Other SMTP email addresses.
• X400: X.400 addresses in on-premises Exchange.
• X500: X.500 addresses in on-premises Exchange.

If you don't include a Type value for an email address, the address is assumed to be an SMTP email address. The syntax of SMTP email addresses is validated, but the syntax of other email address types isn't validated. Therefore, you need to verify that any custom addresses are formatted correctly.

To specify the primary SMTP email address, you can use any of the following methods:

• Use the Type value SMTP on the address.
• The first email address when you don't use any Type values, or when you use multiple lowercase smtp Type values.
• Use the PrimarySmtpAddress parameter instead. You can't use the EmailAddresses parameter and the PrimarySmtpAddress parameter in the same command.

The PrimarySmtpAddress parameter updates the primary email address and WindowsEmailAddress property to the same value.

To replace all existing proxy email addresses with the values you specify, use the following syntax: "Type:EmailAddress1","Type:EmailAddress2",..."Type:EmailAddressN".

To add or remove specify proxy addresses without affecting other existing values, use the following syntax: @{Add="Type:EmailAddress1","Type:EmailAddress2",...; Remove="Type:EmailAddress3","Type:EmailAddress4",...}.

-GrantSendOnBehalfTo

The GrantSendOnBehalfTo parameter specifies who can send on behalf of this mail user. Although messages sent on behalf of the mail user clearly show the sender in the From field (<Sender> on behalf of <Mail user>, replies to these messages are delivered to the mail user, not the sender.

The sender you specify for this parameter must a mailbox, mail user or mail-enabled security group (a mail-enabled security principal that can have permissions assigned). You can use any value that uniquely identifies the sender. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Domain\Username
• Email address
• GUID
• LegacyExchangeDN
• SamAccountName
• User ID or user principal name (UPN)

To enter multiple values and overwrite any existing entries, use the following syntax: Value1,Value2,...ValueN. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

To add or remove one or more values without affecting any existing entries, use the following syntax: @{Add="Value1","Value2"...; Remove="Value3","Value4"...}.

-IgnoreDefaultScope

This parameter is available only in on-premises Exchange.

The IgnoreDefaultScope switch tells the command to ignore the default recipient scope setting for the Exchange PowerShell session, and to use the entire forest as the scope. You don't need to specify a value with this switch.

This switch enables the command to access Active Directory objects that aren't currently available in the default scope, but also introduces the following restrictions:

• You can't use the DomainController parameter. The command uses an appropriate global catalog server automatically.
• You can only use the DN for the Identity parameter. Other forms of identification, such as alias or GUID, aren't accepted.

Type:	SwitchParameter

Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-ImmutableId

The ImmutableId parameter is used by GAL synchronization (GALSync) and specifies a unique and immutable identifier in the form of an SMTP address for an Exchange mailbox used for federated delegation when requesting Security Assertion Markup Language (SAML) tokens. If federation is configured for this mailbox and you don't set this parameter when you create the mailbox, Exchange creates the value for the immutable ID based upon the mailbox's ExchangeGUID and the federated account namespace, for example, 7a78e7c8-620e-4d85-99d3-c90d90f29699@mail.contoso.com.

You need to set the ImmutableId parameter if Active Directory Federation Services (AD FS) is deployed to allow single sign-on into an off-premises mailbox and AD FS is configured to use a different attribute than ExchangeGUID for sign-on token requests. Both, Exchange and AD FS must request the same token for the same user to ensure proper functionality for a cross-premises Exchange deployment scenario.

-MailTip

The MailTip parameter specifies the custom MailTip text for this recipient. The MailTip is shown to senders when they start drafting an email message to this recipient. If the value contains spaces, enclose the value in quotation marks (").

When you add a MailTip to a recipient, two things happen:

• HTML tags are automatically added to the text. For example, if you enter the text: "This mailbox is not monitored", the MailTip automatically becomes: <html><body>This mailbox is not monitored</body></html>. Additional HTML tags aren't supported, and the length of the MailTip can't exceed 175 displayed characters.
• The text is automatically added to the MailTipTranslations property of the recipient as the default value: default:<MailTip text>. If you modify the MailTip text, the default value is automatically updated in the MailTipTranslations property, and vice-versa.

-MailTipTranslations

The MailTipTranslations parameter specifies additional languages for the custom MailTip text that's defined by the MailTip parameter. HTML tags are automatically added to the MailTip translation, additional HTML tags aren't supported, and the length of the MailTip translation can't exceed 175 displayed characters.

To add or remove MailTip translations without affecting the default MailTip or other MailTip translations, use the following syntax:

@{Add="Culture1:Localized text 1","\Culture2:Localized text 2"...; Remove="Culture3:Localized text 3","Culture4:Localized text 4"...}.

CultureN is a valid ISO 639 two-letter culture code that's associated with the language.

For example, suppose this recipient currently has the MailTip text: "This mailbox is not monitored." To add the Spanish translation, use the following value for this parameter: @{Add="ES:Esta caja no se supervisa."}.

-MaxReceiveSize

The MaxReceiveSize parameter specifies the maximum size of a message that can be sent to the mail user. Messages larger than the maximum size are rejected.

When you enter a value, qualify the value with one of the following units:

• B (bytes)
• KB (kilobytes)
• MB (megabytes)
• GB (gigabytes)

Unqualified values are typically treated as bytes, but small values may be rounded up to the nearest kilobyte.

A valid value is a number up to 1.999999 gigabytes (2147483647 bytes) or the value unlimited. The default value is unlimited, which indicates the maximum size is imposed elsewhere (for example, organization, server, or connector limits).

Base64 encoding increases the size of messages by approximately 33%, so specify a value that's 33% larger than the actual maximum message size that you want to enforce. For example, the value 64 MB results in a maximum message size of approximately 48 MB.

Type:	Unlimited

-RejectMessagesFrom

The RejectMessagesFrom parameter specifies who isn't allowed to send messages to this recipient. Messages from these senders are rejected.

Valid values for this parameter are individual senders in your organization (mailboxes, mail users, and mail contacts). You can use any value that uniquely identifies the sender. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Email address
• GUID

You can enter multiple senders separated by commas. To overwrite any existing entries, use the following syntax: Sender1,Sender2,...SenderN. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Sender1","Sender2",..."SenderN".

To add or remove senders without affecting other existing entries, use the following syntax: @{Add="Sender1","Sender2"...; Remove="Sender3","Sender4"...}.

The senders you specify for this parameter are automatically copied to the RejectMessagesFromSendersOrMembers property. Therefore, you can't use the RejectMessagesFrom and RejectMessagesFromSendersOrMembers parameters in the same command.

By default, this parameter is blank ($null), which allows this recipient to accept messages from all senders.

-RejectMessagesFromDLMembers

The RejectMessagesFromDLMembers parameter specifies who isn't allowed to send messages to this recipient. Messages from these senders are rejected.

Valid values for this parameter are groups in your organization (distribution groups, mail-enabled security groups, and dynamic distribution groups). Specifying a group means all members of the group aren't allowed to send messages to this recipient. You can use any value that uniquely identifies the group. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Email address
• GUID

You can enter multiple groups separated by commas. To overwrite any existing entries, use the following syntax: Group1,Group2,...GroupN. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Group1","Group2",..."GroupN".

To add or remove groups without affecting other existing entries, use the following syntax: @{Add="Group1","Group2"...; Remove="Group3","Group4"...}.

The groups you specify for this parameter are automatically copied to the RejectMessagesFromSendersOrMembers property. Therefore, you can't use the RejectMessagesFromDLMembers and RejectMessagesFromSendersOrMembers parameters in the same command.

By default, this parameter is blank ($null), which allows this recipient to accept messages from all groups.

-RejectMessagesFromSendersOrMembers

The RejectMessagesFromSendersOrMembers parameter specifies who isn't allowed to send messages to this recipient. Messages from these senders are rejected.

Valid values for this parameter are individual senders and groups in your organization. Individual senders are mailboxes, mail users, and mail contacts. Groups are distribution groups, mail-enabled security groups, and dynamic distribution groups. Specifying a group means all members of the group aren't allowed to send messages to this recipient.

To specify senders for this parameter, you can use any value that uniquely identifies the sender. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Email address
• GUID

You can enter multiple senders separated by commas. To overwrite any existing entries, use the following syntax: Sender1,Sender2,...SenderN. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Sender1","Sender2",..."SenderN".

To add or remove individual senders or groups without affecting other existing entries, use the RejectMessagesFrom and RejectMessagesFromDLMembers parameters.

The individual senders and groups you specify for this parameter are automatically copied to the RejectMessagesFrom and RejectMessagesFromDLMembers properties, respectively. Therefore, you can't use the RejectMessagesFromSendersOrMembers parameter and the RejectMessagesFrom or RejectMessagesFromDLMembers parameters in the same command.

By default, this parameter is blank ($null), which allows this recipient to accept messages from all senders.

-UMDtmfMap

This parameter is available only in on-premises Exchange.

The UMDtmfMap parameter specifies the dual-tone multiple-frequency (DTMF) map values for the recipient. This allows the recipient to be identified by using a telephone keypad in Unified Messaging (UM) environments. Typically, these DTMF values are automatically created and updated, but you can use this parameter to make changes manually. This parameter uses the following syntax:

• emailAddress:<integers>
• lastNameFirstName:<integers>
• firstNameLastName:<integers>

To enter values that overwrite all existing entries, use the following syntax: emailAddress:<integers>,lastNameFirstName:<integers>,firstNameLastName:<integers>.

If you use this syntax and you omit any of the DTMF map values, those values are removed from the recipient. For example, if you specify only emailAddress:<integers>, all existing lastNameFirstName and firstNameLastName values are removed.

To add or remove values without affecting other existing entries, use the following syntax: @{Add="emailAddress:<integers>","lastNameFirstName:<integers>","firstNameLastName:<integers>"; Remove="emailAddress:<integers>","lastNameFirstName:<integers>","firstNameLastName:<integers>"}.

If you use this syntax, you don't need to specify all of the DTMF map values, and you can specify multiple DTMF map values. For example, you can use @{Add="emailAddress:<integers1>","emailAddress:<integers2>} to add two new values for emailAddress without affecting the existing lastNameFirstName and firstNameLastName values.

• Never: TNEF is never used for any messages sent to the mail user or mail contact. TNEF messages are converted to plain text.
• UseDefaultSettings: TNEF messages aren't specifically allowed or prevented for the mail user or mail contact. Whether TNEF messages are sent to the recipient depends on the remote domain TNEF settings (the default remote domain or a specific remote domain), or the Outlook Rich Text message settings specified by the sender in Outlook.

The default value is UseDefaultSettings.

-WindowsEmailAddress

The WindowsEmailAddress parameter specifies the Windows email address for this recipient. This is a common Active Directory attribute that's present in all environments, including environments without Exchange. Using the WindowsEmailAddress parameter on a recipient has one of the following results:

• In environments where the recipient is subject to email address policies (the EmailAddressPolicyEnabled property is set to the value True for the recipient), the WindowsEmailAddress parameter has no effect on the WindowsEmailAddress property or the primary email address value.
• In environments where the recipient isn't subject to email address policies (the EmailAddressPolicyEnabled property is set to the value False for the recipient), the WindowsEmailAddress parameter updates the WindowsEmailAddress property and the primary email address to the same value.

The WindowsEmailAddress property is visible for the recipient in Active Directory Users and Computers in the E-mail attribute. The attribute common name is E-mail-Addresses, and the Ldap-Display-Name is mail. If you modify this attribute in Active Directory, the recipient's primary email address is not updated to the same value.
