Cannot connect to user mailbox in SBS 2003 through Outlook 2003
Posted on 2009-04-20
I have a user whose Outlook account for some reason will no longer connect to the Exchange 2003 server. I'm not sure what has happened or how, but I receive an error that says "Unable to open your default email folders. The information store could not be opened."
The user is running Outlook 2003 and connected to Exchange 2003 (SBS 2003) and is running in "Cached Mode"
I have run the scanpst.exe on the .ost file and allowed the scan to create a backup of the original file and then allowed it to clean/repair any inconsistancies or problems found - problems were fixed successfully.
I have run a detect and repiar on Outlook successfully.
I have attempted to create a new Outlook Profile to connect to but continue to receive the same errors.
I have started Outlook in "Safe" mode as well, but with no better luck.
I have renamed the .ost file and the C:\Docs and Settings\Username\Local Settings\App data\MS\Outlook file in hopes that upon restarting Outlook, this directory would be recreated. It was, but still no success.
I finally removed the Outlook profile and recreated it and reconfigured the email account to be associated with the Outlook account but continue to receive the same error.
I can however connect to the user's mailboc through OWA on the server to successfully check/send/receive email.
What's interesting too is that I can choose to start Outlook as a different user and connect successfully to this user's mailbox. (Such as Logging into "User A" domain account, starting Outlook as "User B" and configuring to connect to "User A's" mailbox - this works!)
I can also log into the machine as "User B", and configure Outlook to access "User A's" mailbox successfully! However, if I attempt to run Outlook as "User A" and connect to the troublesome mailbox, I receive the same error "Unable to open your default email folders. The information store could not be opened."
I can connect to this user's mailbox using any account other than his... weird.
Any ideas or pointers? I'm at a loss and don't know what to do.
