Final answer:
To cancel a Teams meeting in Outlook, open the Outlook calendar, click the meeting to open its details, choose 'Cancel Meeting', optionally add a message, and click 'Send Cancellation' to notify attendees.
Step-by-step explanation:
To cancel a Teams meeting in Outlook, you will need to open the Outlook calendar and find the meeting you want to cancel. Once you have located the meeting, click on it to open the meeting details. Within these details, you should see an option to Cancel Meeting.
Click this option, and a window will prompt you to send a cancellation email to the attendees. You can add a message explaining why the meeting is cancelled if desired, then click Send Cancellation to notify all attendees that the meeting has been canceled. It is important to note that simply deleting the meeting from your calendar will not notify other attendees of the cancellation, so be sure to follow these steps to properly cancel the meeting and inform the participants.
