Recently, Microsoft put out an update that changes the default meeting type to Teams/online meetings in Microsoft Outlook.

Once you add a required or optional attendee to an event, you might notice Microsoft Teams information is displayed in the message body area of the event.

Please refer to the picture below if you do not want your meeting to be a Teams/online meeting.

 

If you want your meeting to be online, simply send the invites after the appropriate attendees and details have been added to the event.

Please let us know if you have any additional questions or concerns.
