Can not cancel Teams meeting

Question

As the initiator of the meeting, I cancelled the Teams meeting (the meeting on my calendar has disappeared), but the meeting of the participants is still valid (they haven't received the notice of meeting cancellation either).

Answer 1

Dear @Liu, Vincent

Welcome to the Microsoft Q&A Community! 

I understand that as an organizer, you canceled a meeting and still hear from attendees that it remains on their calendars.  

To better understand the situation, could you please confirm whether you canceled the meeting with a cancellation notice, or without sending a notice? This detail determines what should happen on the attendees’ calendars. 

If the meeting was canceled without sending a notice, Outlook and Teams are working as designed. In that case, the meeting is removed from your calendar, attendees are not notified of the change, and the event generally continues to appear on their calendars with a Cancelled label. Because no cancellation message was delivered, each attendee needs to remove the meeting from their calendar manually. This is expected behavior when a notice is not sent.  

In case you did cancel the meeting with a cancellation notice, a notice should be sent to each participant's inbox to confirm the cancellation.

If the meeting is still visible on attendees’ calendars, it may indicate that their Outlook client has not yet refreshed or synchronized with the server. This type of behavior has been reported in scenarios where cancellation updates do not reach all participants or do not apply correctly until Outlook fully reloads.  

In those cases, asking participants to close and reopen Outlook, or switch briefly to Outlook on the web to confirm, may help trigger a proper calendar sync. 

Once you let me know which option you selected, I will outline the most appropriate next steps. Thank you in advance for your patience while we work through this. I am here to help until this is fully resolved.
