We recently moved all of our users over to new post offices. Now, every day or two, I get a call from someone saying that they are getting D101 User Not Found, or something similar, when they send a message to someone either individually or in a group from one of their personal address books (Frequent Contacts or other). The sender isn't always the same, and the recipient isn't always the same so it's not tied to anything specific that I can tell.

I've already gone through and synchronized all mailboxes. I see that GWCheck has a switch called PABFix. Will using this correct the entries in personal address books?
