Use the Exchange Management Shell to change the assignment policy on a mailbox

To change the assignment policy that's assigned to a mailbox, use the following syntax.

Set-Mailbox <mailbox alias or name> -RoleAssignmentPolicy <assignment policy>

This example sets the assignment policy to Engineering Users on the mailbox Brian.

Set-Mailbox Brian -RoleAssignmentPolicy "Engineering Users"

Use the Exchange Management Shell to change the assignment policy on a group of mailboxes assigned a specific assignment policy

Note

You can't use the EAC to change the assignment policy on a group of mailboxes all at once.

This procedure makes use of pipelining, the Where cmdlet, and the WhatIf parameter. For more information about these concepts, see the following topics:

If you want to change the assignment policy for a group of mailboxes that are assigned a specific policy, use the following syntax.

Get-Mailbox | Where {$_.RoleAssignmentPolicy -Eq "<assignment policy to find>"} | Set-Mailbox -RoleAssignmentPolicy <assignment policy to set>

This example finds all the mailboxes assigned to the Redmond Users - No Voicemail assignment policy and changes the assignment policy to Redmond Users - Voicemail Enabled.

Get-Mailbox | Where {$_.RoleAssignmentPolicy -Eq "Redmond Users - No Voicemail"} | Set-Mailbox -RoleAssignmentPolicy "Redmond Users - Voicemail Enabled"

This example includes the WhatIf parameter so that you can see all the mailboxes that would be changed without committing any changes.

Get-Mailbox | Where {$_.RoleAssignmentPolicy -Eq "Redmond Users - No Voicemail"} | Set-Mailbox -RoleAssignmentPolicy "Redmond Users - Voicemail Enabled" -WhatIf

For detailed syntax and parameter information, see Get-Mailbox or Set-Mailbox.
