I have a user with a Mailbox on Exchange 2010 SP2 RU3. The user accesses email via Outlook 2010. When the user tries to add delegates via this route within their Outlook client “File->Account Settings->Delegate Access” they receive this error message “The delegates settings were note saved correctly. Cannon activate send-on-behalf-of list. You do not have sufficient permission to perform this operation on this object. These are my troubleshooting steps and observations:
- The Outlook profile has been re-created for the user.
- I have given myself full access permission to the mailbox and replicate the same issue.
- On further investigation I could see the user didn’t have “send as” permission so I added NT AUTHORITY\SELF, for testing I have also explicitly added the user account.
- I could see some users that were listed as delegates within Outlook, but they had no delegated permission, I am unable to remove these. I tried to remove all of them via adsiedit but only some have visibly been removed in Outlook.
- I also used used ExFolder to modify the permissions.
- Also ran a repair of the mailbox.
- In AD I checked the permission on the mailbox confirming the correct permissions applied to ‘self’. For testing I also explicit added the user. For testing I also gave ‘self’ and the explicit user full control.
- If I delegate access at a lower level such as the calendar etc it does work. It just appears to fail at top level of Outlook.
Any suggestions?
