Delegate Troubles

[Doreen]

I have a user that is having trouble delegating and removing delegation to
his Outlook. I remove the users and when I go back into
Tools--Options--Delegates, they're still in there. When I add a user and
give the user permissions, they're gone if I go back in. (The user is
there, but all the permissions change to "none".)

I removed the Outlook profile and readded it, but it didn't make any
changes.

Any ideas on what I should be looking for? Permissions on the Exchange side
seem to be set properly.

Thanks!
