How to delete recurring calendar invites from a deleted contact?

Question

We have a recurring monthly calendar invite that was originally created by a contact who is no longer with our organization. The invite is still showing up on our calendars and continues to include more than 30 people.

The issue:

• The organizer's profile has been deleted.
• The meeting appears to be a Zoom invite (but we are not sure of that).
• We are unable to cancel or delete the event from our side.
• The invite keeps popping up every month despite the user account no longer existing.

How can we remove or cancel this recurring meeting from everyone’s calendars when the original organizer is no longer active?

Hi Paul,

Thank you for reaching out regarding the recurring calendar invite that continues to appear despite the original organizer’s account having been deleted.

Since the meeting was created by a user who is no longer active and cannot be accessed through standard Outlook controls, and you're using the new Outlook for Windows, we recommend the following approach:

1. Use Exchange Online PowerShell
   If the deleted user’s mailbox still exists (e.g., in a soft-deleted state), an administrator can run the following command to remove the recurring meeting from all attendees’ calendars:
   Connect-ExchangeOnline
   Remove-CalendarEvents -Identity "
2. If the mailbox is permanently deleted
   Unfortunately, if the mailbox has been purged from Exchange Online, the recurring meeting cannot be removed centrally. In this case, each attendee must manually delete the series from their own calendar.
3. Zoom-Linked Meetings
   If the invite is linked to Zoom, we recommend checking with your Zoom administrator to disable or delete the recurring meeting from the Zoom portal. This may help prevent future notifications or join links from being sent.
4. Alternative Workaround
   If the above options are not viable, consider restoring the deleted user temporarily (if within 30 days), assigning a license, and then accessing the calendar to cancel the meeting manually.

I hope you find this helpful. Please don’t hesitate to reach out again if you need further assistance.
