Microsoft Teams button missing from Outlook Classic Desktop Calendar

Common problem these days. Microsoft offered Teams to anyone awhile back, so many of my clients have found they can use it to attend meetings but to schedule meetings, it’s not functioning in the app or in Outlook Classic calendar. The reason is that they are logged into Teams using a personal Microsoft account.

To get the button to show up in Outlook Desktop Calendar:

  • Log into your Microsoft 365 Business account
  • Go to Teams www.teams.microsoft.com
  • Click on the 3 vertical dots next to your name in the upper right
  • Click on “Get the desktop app”
  • Close Outlook
  • Install the desktop Teams app
  • Once complete, launch Outlook Classic
  • The two Teams buttons should show up. If they don’t, you might have other issues to repair first.
