Hello Everyone, We are currently seeing an issue when we change the delegate of a resource mailbox, the new and old delegates are getting the requests. The old delegate is not associated with the resource in any way and has been verified many times. The Version we are running is MS Exchange 2010 SP2. Steps we have tried is creating a new resource mailbox and changing delegates which does work, the problem exists with resources created months and years ago. Any help on this would be appreciated. Thanks.

In outlook save all his rules, than run outlook /cleanrules this should purge any hidden\orphaned delegates. Then go back in and add the new delegate again and add the rules back.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Please explain how you are changing the delegate.. can you provide the output of the powershell before / after changing the delegate

Hi You can try to use a tool called MFCMAPI to remove the delegate rules from those affected mailboxes. Hope it works You can download mfcmapi from http://www.microsoft.com/en-us/download/details.aspx?id=2953 CheersZi Feng TechNet Community Support
