I have an odd problem heres what has happened.

1. Created a user and a mailbox. (SBS 2000)
2. Logged in as that user opened outlook and assigned 3 users as
delegates with full permissions.
3. Went to a delegate computer and in the advanced tab (Outlook XP)
added the user that was created as a mailbox to be opened when Out
look opens.
4. When opening Outlook on the client computer, It comes up in the
list but when clicking on the users mailbox I get the message.."Unable
to display the folder. Microsoft Outlook could not access the
specified folder location. The operation failed"

5. If I go File-Open-Other Users mailbox, I can in fact view the
mailbox. And see email in it and reply and so on.

One thing I did do which may have had an impact was when I created the
user and Mailbox, I made an error with the display name, and I removed
the user and Mailbox, and recreated it with the only change being the
display name.

Have tried, Rebooting, Deleting and recreating again, deleting the
client outlook profile and recreating it. I feel it must be in
Exchange but am unsure what to do next.

Any help would be appreciated.

TIA
