Applies to: Exchange Server 2016

This cmdlet is available only in on-premises Exchange Server 2016.

Use the Remove-SiteMailboxProvisioningPolicy cmdlet to remove site mailbox provisioning policies.

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

Remove-SiteMailboxProvisioningPolicy -Identity <MailboxPolicyIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

This example deletes the site mailbox policy named Default that was created when you installed Microsoft Exchange. This example assumes that you have already designated another policy as the default.

Remove-SiteMailboxProvisioningPolicy -Identity Default

You can't delete the default site mailbox provisioning policy. You need to create a new default policy by using the New-SiteMailboxProvisioningPolicy cmdlet, or designate an existing policy as the default policy by using the Set-SiteMailboxProvisioningPolicy cmdlet.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Site mailbox provisioning policy" entry in the Sharing and collaboration permissions topic.


Parameter Required Type Description




The Identity parameter specifies the site mailbox provisioning policy that you want to remove. You can use any value that uniquely identifies the policy. For example:

  • Name

  • Distinguished name (DN)

  • GUID




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.




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.




The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.

To see the input types that this cmdlet accepts, see Cmdlet Input and Output Types. If the Input Type field for a cmdlet is blank, the cmdlet doesn’t accept input data.

To see the return types, which are also known as output types, that this cmdlet accepts, see Cmdlet Input and Output Types. If the Output Type field is blank, the cmdlet doesn’t return data.
