I have an odd problem that I cannot find a solution for, nor can I think where to start to get to the bottom it. We have a number of Exchange 2003 servers in our organisation. They are divided up into 'regions' with mailboxes and public folders hosted pertaining to their relevant regions on each.
Recently, a handful of users have suddenly started to receive everyone's favourite "Connect to..." box asking for network credentials when opening Outlook configured to use Cached Mode. Previous to this everything was working just fine.
The perculiarity is that the server mentioned in this box that Outlook is trying to log on to is *not* the server that their mailbox resides on. In all cases it is the same server that wants credentials but I cannot for the life of me work out why. If you open Outlook in standard mode it works just fine, it is only in cached mode that the problem appears. If you persistently try and log on to this 'wrong' server eventually it goes away and Outlook then carries on working no problems.
I have tried all the usual suspects of looking for mailboxes opening from this box as part of their profile, any old Public Folder favourites they may have etc. and have come up with nothing so far.
Anybody have any suggestions? Even a pointer in the right direction is good enough.
