Cannot assign delegate permissions

We've got a user who is unable to assign permissions to delegates in Outlook. He can add the delegates but the permissions are not saved.

When he does this on Outlook 2002 on Windows 2000, he gets the error message "The Delegates settings were not saved correctly. Unable to modify access control list.".

When he does this on Outlook 2003 on Windows 2003 (Terminal Services), there's no error message but after setting the delegate permissions, closing and re-opening the Options dialog, all delegate permissions are "None" again.

This problem does appear to be specific one user. Can anyone suggest any way of fixing this?

(Active Directory in mixed mode on Win2003 controllers, Exchange 2003 on Win2003).

Check if he has FULL control on his own mailbox.

In AD Users and Computers. under "Mailbox Rights", "Full mailbox access" is checked for this user.

This problem was caused by the user having an existing delegate that was a distribution list, not a user or security group.

When this is the case, you get a series of messages in the Application log on the Exchange server:

  MSExchangeIS event 1233, and
  MSExchangeIS Mailbox Store event 9556 (which contains the name of the offending group).

Removing the distribution list from the list of delegates fixed this problem.
