Recurring meeting after the owner mailbox deleted?

Question

Hi Team,

This cmdlet https://learn.microsoft.com/en-us/powershell/module/exchange/remove-calendarevents?view=exchange-ps will not work when the mailbox has been deleted from both OnPremise AD DS and Azure AD.

After the mailbox license is revoked and force deleted from the https://admin.microsoft.com/Adminportal/Home?source=applauncher#/deletedusers and Azure AD, what happens to the recurring calendar appointment sent out by the mailbox?

is it automatically deleted or left as an orphaned meeting, which can only be deleted by the Meeting Room Full Delegate permission?

Any help would be greatly appreciated.

Hi @EnterpriseArchitect ,

the mailbox has been deleted from both OnPremise AD DS and Azure AD

For recurring meetings, it is not automatically deleted and will left as an orphaned meeting.The best way for cancel the meetings is granting the mailbox delegate permission and entering the mailbox to cancel the meeting events.
Because the owner's mailbox for the meeting has been deleted, we recommend that you could use New-ComplainceSearch command if you want to delete meetings in bulk.

new-ComplianceSearch -Name "DeleteMeeting" -ContentMatchQuery "kind:meetings AND from:******@user.onmicrosoft.com" -ExchangeLocation all  
Start-ComplianceSearch -identity "DeleteMeeting"  
New-ComplianceSearchAction -SearchName "DeleteMeeting" -Purge  

Moreover, you can use the following two commands to observe the progress of the process.

get-ComplianceSearch  
get-ComplianceSearchAction  

Kindly note: A maximum of 10 items per mailbox can be removed at one time.

In my experience its left as an orphaned meeting. (I might be in error)

All users would need to erase it and the recurrence, as if a new user would need to send a new meeting convocation as he would be unable to update the recurring meeting.
