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

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

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

	Copy Code
Set-Mailbox Brian -RoleAssignmentPolicy "Unified Messaging Users"

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Assignment policies" entry in the Role Management Permissions topic.

Note:
You can't use the Exchange Management Console (EMC) 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:

• Pipelining
  
  
• Working with Command Output
  
  
• WhatIf, Confirm, and ValidateOnly Switches
  
  

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

	Copy Code
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.

	Copy Code
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.

	Copy Code
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.
