Check that the Teams Add-in isn’t disabled

If the Teams add-in still isn’t working, make sure that it isn’t disabled. Go to the ‘File’ tab from the Outlook ribbon.

Then, go to ‘Options’ from the bottom-left part of the screen.

A dialog box for Outlook Options will open. Go to ‘Add-ins’ from the navigation pane on the left.

See that the ‘Microsoft Teams Meeting Add-in for Microsoft Office’ isn’t listed under Disabled Application Add-ins.

If it is, select ‘COM Add-ins’ from the drop-down menu at the bottom and click ‘Go’.

Then, find the option for Microsoft Teams Meeting Add-in for Microsoft Office and click the checkbox next to it to enable it. Click ‘OK’ to add it. Then, restart Outlook.

Run the Troubleshooter

If it still isn’t working, click this link for the Teams Add-in for Outlook missing. Click ‘Open’ on the dialog box on the page. The automated troubleshooter will run and try to fix the problem for you. Follow the instructions on the screen.

If it still doesn’t work, download and install the Microsoft Recovery Support Assistant and follow the instructions on-screen for automated troubleshooting.
