I've seen this error a few times in outlook (e2k7sp1 outlook 2007). I could see it happening if i had made changes to autodiscover, but none had been made and this error seems to have randomly appeared to different users at different times. Has anyone else seen this? John

Does anyone have a solution for this? It is happening in my environment also. This dialog box will randomly appear to users although no mailbox moves occurred. Same setup as knightly (E2k7Sp1 and Outlook 2K7). Thanks.
