Cannot start Outlook

[Magnus Blomberg]

Hi there!

I have a major problem for one user connecting directly to an Exchange
server. She can't start Outlook 2003 from ANY MACHINE, and get the error
message:
"Unable to open your default e-mail folders. The Microsoft Exchange Server
computer is not available. Either there are network problems or the
Microsoft Exchange Server computer is down for maintenance."
With Outlook 2000, and Outlook 2003 using IMAP everything works fine.
I have run "Outlook.exe /rpcdiag" and it gives me no error message, but the
last thing I see before the error message appear is that it's trying to
connect to public folders, which are not located at the same server as her
mailbox.

We are a huge organization and our master domain has recently been upgraded
to AD, but everything works for other users.
I don't know if it's important, but she has been away from work for a year.

Please help
/Magnus

Sounds like you may alternatively have a problem with the user's Outlook
profile. This may be the case if the username has changed in which case
Outlook is supplying the wrong credentials to Exchange.
