Remove a meeting from your Outlook calendar when the meeting isn’t necessary and you want to let the meeting attendees know the meeting is cancelled.
Note: You can only cancel meetings that you organized. If you were invited to a meeting that you want to delete from your calendar, see Delete a meeting.
Switch to your Calendar and find the meeting.
Double-click the meeting to open it.
On the ribbon, click Cancel Meeting.
The meeting form will change into a meeting cancellation form. Type a message to let the attendees know the meeting is cancelled. It’s not necessary, but it helps to avoid confusion.
Click Send Cancellation.
The meeting, including any meeting agenda, notes, and attachments, will be deleted from Outlook.
Only the meeting organizer—the person who sends a meeting request—can send a meeting update or a cancellation.
If you want to cancel one or all meetings that are part of a recurring series, see Cancel all future meetings in a series.
