Applies to: Exchange Online, Exchange Server 2016

This cmdlet is available in on-premises Exchange Server 2016 and in the cloud-based service. Some parameters and settings may be exclusive to one environment or the other.

Use the Remove-RoleAssignmentPolicy cmdlet to remove existing management role assignment policies from your organization.

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

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

This example removes the assignment policy End User Policy. First, find all the mailboxes assigned the assignment policy.

Get-Mailbox | Where {$_.RoleAssignmentPolicy -Eq "End User Policy"}

Next, use the list you gathered to assign each mailbox a new assignment policy. You may want to assign all the mailboxes the same new assignment policy, such as Seattle End User Policy.

Get-Mailbox | Where {$_.RoleAssignmentPolicy -Eq "End User Policy"} | Set-Mailbox -RoleAssignmentPolicy "Seattle End User Policy"

Then, remove all the management role assignments assigned to the previous assignment policy End User Policy.

Get-ManagementRoleAssignment -RoleAssignee "End User Policy" | Remove-ManagementRoleAssignment

Finally, remove the assignment policy.

Remove-RoleAssignmentPolicy "End User Policy"

The assignment policy you want to remove can't be assigned to any mailboxes or management roles. Also, if you want to remove the default assignment policy, it must be the last assignment policy. Do the following before you attempt to remove an assignment policy:

  • Use the Set-Mailbox cmdlet to change the assignment policy for any mailbox assigned the assignment policy you want to remove.

  • If the assignment policy is the default assignment policy, use the Set-RoleAssignmentPolicy cmdlet to select a new default assignment policy. You don't need to do this if you're removing the last assignment policy.

  • Use the Remove-ManagementRoleAssignment cmdlet to remove any management role assignments assigned to the policy.

For more information about assignment policies, see Understanding management role assignment policies.

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 "Assignment policies" entry in the Role management permissions topic.


Parameter Required Type Description




The Identity parameter specifies the assignment policy to remove. If the assignment policy name has spaces, enclose the name in quotation marks (").




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.




This parameter is available only in on-premises Exchange 2016.

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,

The DomainController parameter isn't supported on Edge Transport servers. An Edge Transport server uses the local instance of Active Directory Lightweight Directory Services (AD LDS) to read and write data.




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.
