A recurring meeting was scheduled for 100 users from a shared mailbox. A user with a full permission on the shared mailbox cancelled the meeting. However, the recipients didnt get the cancelled notification and the recurring meeting lies in their mailboxes.

Hi,

As an Exchange Online Administrator, you can try to accomplish this using cmdlets.Use New-ComplianceSearch (ExchangePowerShell) | Microsoft Learn to filter to the meeting you want to cancel.

And then use Start-ComplianceSearch (ExchangePowerShell) | Microsoft Learn to ensure that you are searching for the meeting you want to cancel. The final step is to use New-ComplianceSearchAction (ExchangePowerShell) | Microsoft Learn to cancel the meeting.

Below are some examples:

New-ComplianceSearch -Name "RemoveRecurringMeeting" -ExchangeLocation All -ContentMatchQuery '(Subject:"<Meeting Subject>" AND Kind:Meetings)'

Start-ComplianceSearch -Identity “RemoveRecurringMeeting”

New-ComplianceSearchAction -SearchName “RemoveRecurringMeeting” -Purge -PurgeType SoftDelete
