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.<br />
<br />
When I go into EMC and try to remove the permission I get the error &quot;Can't remove the access control entry on the object...because the ACE doen't exist on the object.&quot;<br />
<br />
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.<br />
<br />
The user mailbox is gaile and the user that has permission that needs to be removed is zack.
