Exchange 2003 on W2K domain, native mode. We disabled 3 accounts this morning and then re-enabled them less than an hour later. When they try to open Outlook, they get a message that the attempt to log on to the Microsoft Exchange server has failed. Everyone else is able to get in to their mailboxes fine. The account shows enabled in AD. The mailbox doesn't have an X in it. I recreated the RUS and that didn't correct the problem. It's been an hour and a half, so I'm not waiting for replication. Thoughts anyone? Paul Maglinger, A+, CA, CCA, CET, MCSE Systems Administrator Shoe Carnival Inc. (812)867-4674 pmaglinger@xxxxxxxx ________________________________
