Delegate permissions not working for 1 user

[Neil]

I have Outlook 2000 / Exchange 2000, several users have Send on Behalf of
permissions for the Boss and have for some time with no issues. I've been
trying to add another user and the Send on Behlaf of permissions don't seem
to take. I have specified her as a delegate, she has the exact same
permissions as the other (working) users in both the Boss's delegate/inbox
permissions and Windows Active Directory on our domain. I can find no
difference in permissions between this user and the other working users.

The user in question even gets an e-mail every time I change her
permissions, which tells her that she can now create e-mails on the Boss's
behalf, but when she tries to send a message for him (by choosing his name in
the From field of a new e-mail message) it says she does not have permission
to send a message for this user. Am I missing something here?

I still have found no resolution on this issue, despite posting this problem
to several forums and messageboards on the Internet. I'm replying to my
original post in the hope that someone new might see this message and have
some advice.
