[<CommonParameters>]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.
In Exchange Server, the CommonParameters InformationVariable and InformationAction don't work.
Examples
Example 1
$password = Read-Host "Enter password" -AsSecureString
New-Mailbox -UserPrincipalName chris@contoso.com -Alias chris -Database "Mailbox Database 1" -Name ChrisAshton -OrganizationalUnit Users -Password $password -FirstName Chris -LastName Ashton -DisplayName "Chris Ashton" -ResetPasswordOnNextLogon $trueThis example creates a user Chris Ashton in Active Directory and creates a mailbox for the user. The mailbox is located on Mailbox Database 1. The password must be reset at the next logon. To set the initial value of the password, this example creates a variable ($password), prompts you to enter a password, and assigns that password to the variable as a SecureString object.
Example 2
New-Mailbox -UserPrincipalName confmbx@contoso.com -Alias confmbx -Name ConfRoomMailbox -Database "Mailbox Database 1" -OrganizationalUnit Users -Room -ResetPasswordOnNextLogon $trueThis example creates a user in Active Directory and a resource mailbox for a conference room. The resource mailbox is located in Mailbox Database 1. The password must be reset at the next logon. You are prompted for the value of the initial password because it's not specified.
Example 3
New-Mailbox -UserPrincipalName confroom1010@contoso.com -Alias confroom1010 -Name "Conference Room 1010" -Room -EnableRoomMailboxAccount $true -RoomMailboxPassword (Get-Credential).passwordThis example creates an enabled user account in Active Directory and a room mailbox for a conference room in an on-premises Exchange organization. The RoomMailboxPassword parameter prompts you to enter the password for the user account.
Example 4
New-Mailbox -Shared -Name "Sales Department" -DisplayName "Sales Department" -Alias Sales
Set-Mailbox -Identity Sales -GrantSendOnBehalfTo MarketingSG
Add-MailboxPermission -Identity Sales -User MarketingSG -AccessRights FullAccess -InheritanceType AllThis example creates the shared mailbox "Sales Department" and grants Full Access and Send on Behalf permissions for the security group "MarketingSG". Users who are members of the security group will be granted the permissions to the mailbox.
This example assumes that you've already created a mail-enabled security group named "MarketingSG" by using the New-DistributionGroup cmdlet.
Parameters
-AccountDisabled
This parameter is available only in on-premises Exchange.
The AccountDisabled switch specifies that the user account associated with the mailbox is disabled. You don't need to specify a value with this switch.
The mailbox is created, and the associated account is created, but the account is disabled, so you can't log on to the mailbox.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 |
-ActiveSyncMailboxPolicy
The ActiveSyncMailboxPolicy parameter specifies the mobile device mailbox policy that's applied to the mailbox. You can use any value that uniquely identifies the policy. For example:.
- Name
- Distinguished name (DN)
- GUID
If you don't use this parameter, the default mobile device mailbox policy is used.
| Type: | MailboxPolicyIdParameter |
| 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 |
-AddressBookPolicy
This parameter is available only in on-premises Exchange.
The AddressBookPolicy parameter specifies the address book policy that's applied to the mailbox. You can use any value that uniquely identifies the address book policy. For example:
- Name
- Distinguished name (DN)
- GUID
For more information about address book policies, see Address book policies in Exchange Server.
| Type: | AddressBookMailboxPolicyIdParameter |
| 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 |
-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.

-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.

-IsExcludedFromServingHierarchy
The IsExcludedFromServingHierarchy parameter prevents users from accessing the public folder hierarchy on this public folder mailbox. For load-balancing purposes, users are equally distributed across public folder mailboxes by default. When this parameter is set on a public folder mailbox, that mailbox isn't included in this automatic load-balancing and won't be accessed by users to retrieve the public folder hierarchy. However, if an administrator has set the DefaultPublicFolderMailbox property on a user mailbox to a specific public folder mailbox, the user will still access the specified public folder mailbox even if the IsExcludedFromServingHierarchy parameter is set for that public folder mailbox.
