Thomas, Are the users getting mail from an Exchange server? I ask because I'd like to know whether it is a client- only or client & server interaction issue. Are the executable and other files needed for Outlook locked down by group or user? If so, and IDs have gotten all screwed up, you may have to make new groups and assign rights to files/directories again. :-( Just guessing, Troy >>> thudak at sistina.com 08/20/01 03:52PM >>> I recently ran into a serious issue with the way outlook does a number of things. (This may in part be w2k's fault as well.) Recently after downgrading our samba PDC from 2.2.1a to 2.2.0, outlook no longer runs for users. After the downgrade went in place, the w2k machines lost their trust accounts and needed to be re-added to the domain. This includes the users on that box. (Which are assigned a completely unique ID every single time they are added, whether it's the same user or not.) My only conclusion is that in re-establishing the trust account and re-adding the users, outlook no longer runs, with an all-to-informational error of "Cannot start microsoft outlook" and nothing more. I think that some registry setting is expecting a different UID than it's receiving upon execution of Outlook by the newly re-added user. This has the side effect of not being able to run Outlook in any way by that user, on that workstation. If anyone has run into this problem, I would be very interested in finding out what you did, until then I'll be scouring registry entries for anything dealing with a uid or outlook, and playing until it works again. (No, not even a re-install seems to do the trick.) I'm very disturbed that this behavior exists and I am very interested in knowing why, so at a very minimum I can get my users functional again. Any suggestions are MORE than appreciated, I've already spent WAY TO LONG on this little fit w2k/o2k is throwing and I'm about to format/reinstall all of those users from scratch.
