[<CommonParameters>] Description
Site mailbox provisioning policies apply settings to new site mailboxes that you create. You can create multiple site mailbox provisioning policies, but only the default policy is followed when users create site mailboxes. The default site mailbox provisioning policy is named Default.
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-SiteMailboxProvisioningPolicy -Identity Default -MaxReceiveSize 25MBThis example changes the site mailbox provisioning policy named Default to allow the maximum size of email messages that can be received by the site mailbox to 25 MB.
Example 2
Set-SiteMailboxProvisioningPolicy -Identity Default -IssueWarningQuota 9GB -ProhibitSendReceiveQuota 10GBThis example changes the warning quota to 9.5 GB and the prohibit send and receive quota to 10 GB.
Example 3
Set-SiteMailboxProvisioningPolicy -Identity SM_DefaultPolicy -AliasPrefix ProjectThis example changes the default provisioning policy named SM_DefaultPolicy and sets the AliasPrefix value to Project. When you create new site mailboxes, the prefix Project- is automatically added to the alias.
Parameters
-AliasPrefix
The AliasPrefix parameter specifies the custom text prefix to add to the aliases of new site mailboxes. Valid values are:
- A text string that's 8 characters or less. When you specify a text value, the value of the DefaultAliasPrefixEnabled parameter ignored and aliases get the text prefix you specified.
- The value $null. This is the default value. The results of this value depend on the DefaultAliasPrefixEnabled parameter value. When it's $true, aliases get the default prefix text. When it's $false, aliases don't get any prefix text.
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 |
-Confirm
The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.
- Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax:
-Confirm:$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.
| Type: | SwitchParameter |
| Aliases: | cf |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 |
-DefaultAliasPrefixEnabled
The DefaultAliasPrefixEnabled parameter specifies whether new site mailboxes have the default prefix text added to the alias. Valid values are:
- $true: Aliases get the default prefix text. This is the default value. In Microsoft 365, the default prefix text is
SMO-(for example, the alias valueBugBash_2016becomesSMO-BugBash_2016). In on-premises Exchange, the default prefix text isSM-(for example, the alias valueBugBash_2016becomesSM-BugBash_2016). - $false: Aliases don't get the default prefix text.
The value of this parameter is related to the value of the AliasPrefix parameter. If you specify a text string for AliasPrefix, the DefaultAliasPrefixEnabled value is ignored. Specifying a text value for AliasPrefix automatically sets the value to $false, but even if you set it to $true, the default alias prefix text isn't used.
| Type: | Boolean |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 |
-DomainController
The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.
| Type: | Fqdn |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 |
-Identity
The Identity parameter specifies the identity of the site mailbox provisioning policy that you want to edit. You can use any value that uniquely identifies the policy. For example:
- Name
- Distinguished name (DN)
- GUID
| Type: | MailboxPolicyIdParameter |
| Position: | 1 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 |
-IsDefault
The IsDefault switch specifies that the site mailbox provisioning policy is the default policy. You don't need to specify a value with this switch.
You can have multiple policies, but only the default policy is followed when users create site mailboxes.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 |
-IssueWarningQuota
The IssueWarningQuota parameter specifies the warning threshold for the size of the mailbox. If the mailbox reaches or exceeds this size, the user receives a descriptive warning message.
A valid value is a number up to 1.999999999 terabytes (2199023254528 bytes) or the value unlimited. When you enter a number, you can qualify it with one of the following units:
- B (bytes)
- KB (kilobytes)
- MB (megabytes)
- GB (gigabytes)
- TB (terabytes)
Unqualified values are typically treated as bytes, but small values may be rounded up to the nearest kilobyte.
The IssueWarningQuota value must be less than or equal to the ProhibitSendReceiveQuota value.
The default value is 49 GB.
| Type: | ByteQuantifiedSize |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 |
-MaxReceiveSize
The MaxReceiveSize parameter specifies the maximum size of a message that can be sent to the site mailbox. 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 (2147482624 bytes) or the value unlimited. The default value is 36 MB.

-Name
The Name parameter specifies the unique name of the site mailbox provisioning policy. The maximum length is 64 characters. If the value contains spaces, enclose the value in quotation marks (").
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 |
-ProhibitSendReceiveQuota
The ProhibitSendReceiveQuota parameter specifies a size limit for the mailbox. If the mailbox reaches or exceeds this size, the mailbox can't send or receive new messages. Messages sent to the mailbox are returned to the sender with a descriptive error message. This value effectively determines the maximum size of the mailbox.
A valid value is a number up to 1.999999999 terabytes (2199023254528 bytes) or the value unlimited. When you enter a number, you can qualify it with one of the following units:
- B (bytes)
- KB (kilobytes)
- MB (megabytes)
- GB (gigabytes)
- TB (terabytes)
Unqualified values are typically treated as bytes, but small values may be rounded up to the nearest kilobyte.
The value must be greater than or equal to the ProhibitSendQuota or IssueWarningQuota values.
The default value is 50 GB.
| Type: | ByteQuantifiedSize |
