http://www.msexchange.org -------------------------------------------------------Any time Windows "Users" UI shows the RID instead of the domain\username, that user no longer exists. The good news is that this RID cannot be used; either by an existing or future user. No one can log on or impersonate this now-defunct account. While this may be annoying, it's far less critical than other issues you can probably solve for this customer (such as "change my 'public' name in the GAL") that don't include changing the permissions on the entire Exch management system.

I have also looked through the GPO to see if I can find the user in question but haven't had any luck find it. I tried to click Advanced and remove the inherent option, then clicked copy, but when I clicked applied after removing the above account I was told that 27 rights would be changed; so I aborted it. I am open to suggestions how I can remove this user without screwing up the rest of the rights on Exchange. Thanks!
