Outlook for Microsoft 365

Last Updated: August 6, 2024

ISSUE

After updating to New Teams, you notice the following issues: 

• When you go to the Outlook Desktop calendar to create a meeting, the Teams Meeting button is missing.

• When you check Outlook Desktop for the Teams Meeting Add-in by going to File > Options > Add-ins, then select Go next to COM Add-ins, the Teams Meeting Add-in is missing.

This issue happens if the update to New Teams did not properly install the Teams Meeting Add-in.

STATUS: RESOLUTION

The steps below will result in New Teams installing the Teams Meeting Add-in.

1. Uninstall the Teams Meeting Add-in by right clicking the Windows Start button and select Settings > Apps > Installed Apps, then search for the Teams Meeting Add-in.

3. Close Outlook.

4. Close Teams from the System Tray by right clicking on the Teams icon in the System Tray and select Quit.
    

5. Restart New Teams. This will force New Teams to reinstall the Teams Meeting Add-in which should fix the issue. When you see Teams Meeting Add-in in the list of installed apps again, restart Outlook and it should be working again.
