Like most, we've mograted from Exchange 2003 to 2010. We want to remove some of the older permissions that were set on users mailboxes for manager access, etc.
When I go into EMC and try to remove the permission I get the error "Can't remove the access control entry on the object...because the ACE doen't exist on the object."
Assuming there is a PowerShell command to remove this, can someone assist. I am very tentative in PowerShell, so as much assistance as possible would be greatly appreciated.
The user mailbox is gaile and the user that has permission that needs to be removed is zack.
