Exchange Server - Unable to open mailbox in MS Outlook client
Asked By chris

All,
I have a user with a problem where she cannot open her Exchange 2003 mailbox
using Microsoft Outlook 2003 or 2000. She is getting the error:
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.
The server is definitely up and running. I have her using OWA for now. I
initially thought it was an Outlook issue on her machine, since I could
connect to her mailbox logged on as the administrator on my laptop, but when
I logged onto my laptop with her acct, I get the same error. Its definitely
something with her AD account. But the wierd thing is its only for OUtlook
profiles, not OWA
I thought maybe the RPC client registry values were missing but they were
there.
I check her AD acct but I dont see anything different on her acct. I know
you can disable OWA, POP, IMAP but there's nothing to disable MAPI profile
access.
Has anyone seen this problem before? Luckily, she can get to mail through
OWA but users prefer the full client. Any help is appreciated.

Did you check name resolution (DNS and WINS) and the personal firewall
settings on the client machine?
