Original KB number:   3201352

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 MFCMAPI.
  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.
