Delegate receives multiple or duplicate meeting requests in Outlook

Symptoms

 In Microsoft Outlook, a delegate receives multiple or duplicate meeting requests in their Inbox. 

Cause

This issue occurs when there are multiple hidden delegate rules in the Manager's mailbox, or when there's a corrupted delegate rule.

Resolution

To resolve this issue, follow these steps:
  1. Close the Manager's and Delegate's Outlook clients.
  2. Download and start Microsoft Foundation Classes MAPI (MFCMAPI) on a computer that has Outlook installed. To do this, go to http://mfcmapi.codeplex.com.
  3. Go to Quick Start, and then select Inbox Rules. If you're prompted, select the manager profile.
  4. Find the rule whose PR_RULE_PROVIDER option is set to SCHEDULE+ EMS Interface, and then delete it.
  5. Start Outlook by using the Manager profile: File<-Account Settings<-Delegate Access. Then, remove the delegate.
  6. Restart Outlook.
  7. Add the delegate to the Manager profile.
