In managing a large enterprise environment of 5400 mailboxes, Exchange Server 2010 SP3, i am running into the following problem. In reviewing the Manage Full Access Permissions for various mailboxes you will find Orphaned SID's from users long gone. I have been searching for quite a long time for a method to remove the Orphaned SID's from all the mailboxes.
I have already used the following 'RemoveBadSid.ps1' which does not touch these and only affects the bad SID's in AD not Exchange. I cleaned those up already.
Is there a simple tool to use ?
Any help would be appreciated.
