Exchange 2007 when sending a calendar invite, a non-existent delegate shows up in an undeliverable message RRS feed

  • Question

  • I had a test user that was removed. When it was removed, it was still listed as a delegate on someone's email. Now, whenever a Calendar invite is sent to the existing user, the sender receives an undeliverable message. The existing user does not receive notification of a calendar event, but the event does show up in the calendar.

  • Hi,

    If the delegate user account or mailbox has been removed from domain or Exchange server, please also remove the delegate settings with this account.

    If a user is set as a delegate for a manager, the meeting request which is send to the Manager would be forwarded to the delegate automatically and ask for approving in the delegate side.

    Please do the following steps in the Manager’s Outlook client to remove the delegate settings for this non-existent delegate:

    1. Open the Manager’s Outlook.

    2. Click File > Account Settings > Delegate Access.

    3. In the Delegate list, click the non-existent delegate, click Remove.

    4. Click OK to save the settings.

    Then check whether the issue persists.
