Hello,

I have a big problem on the Outlook calendar of a meeting room: I see recurring meetings created by a user who left the company a long time ago (his account no longer exists in the AD) and these meetings are booked on a meeting room that no longer exists (old email address of the resource). Yet these meetings continue to appear on the current resource (meeting has been create in 2014...). How to remove these recurring meetings that pollute the meeting room calendar please ? We use Exchange-online and Outlook 2019 in M365 environment. Thank you for your help.

    Hi @shaka ,
    Has his account been deleted from AD for more than 30 days? If not, you could restore his account and cancel the meetings, if yes, then you could use the following methods:

    1.Open calendar in outlook and double-click on the meeting - it should give you a popup asking whether you want to open "this meeting" or "this series". Choose the latter and in the following popup, choose delete (this option is nestled where the "New Email" button sits typically). This will remove the meeting from your calendar. If you need to do it for all other members as well, send a "reply all" on the invite with these instructions prior to deleting the meeting series.

    2.Get permission to cancel meetings in all user mailboxes using the cmdlet:

    Remove-CalendarEvents -Identity <mailbox email address> -CancelOrganizedMeetings -QueryWindowInDays 120  
    

    Since there is no way to change the organizer of the meeting, which can all be a great deal of work, you can refer to:

    Hi @Jame Xu-MSFT ,

    his account has been deleted since years. As it doesn't exist anymore, I dont know how to cancel these meetings from Powershell. Is there a way to connect to the ressource's mailbox (meeting room here) in order to cancel certains meetings from their names please ?
