The Teams Meeting button disappears when Outlook switches the Teams add-in off. Re-enable it in Outlook’s add-in settings, then close and reopen Teams and Outlook, Teams first. If it is still missing, Teams needs repairing or reinstalling, and your IT team should check the add-in is allowed.
Steps for classic Outlook on Windows
- Close Outlook and Teams completely, including the system tray.
- Open Teams and sign in. Wait until it has loaded.
- Open Outlook and go to File > Options > Add-ins.
- At the bottom, set Manage to COM Add-ins and select Go.
- Tick Microsoft Teams Meeting Add-in for Microsoft Office. If it has been disabled, set Manage to Disabled Items, select Go and re-enable it.
- Select OK and restart Outlook. The Teams Meeting button should be back on the Calendar ribbon.
If the add-in is not in the list
- Install or update the Teams desktop app, sign in, then restart the PC.
- Sign out of Teams, close it and reopen it so the add-in registers again.
- Check Outlook and Teams are both up to date and both 64-bit or both 32-bit.
New Outlook and Outlook on the web
The Teams add-in is built in. If the button is missing, your admin may have restricted add-ins or meeting scheduling in the Teams admin centre.
When to ask your IT team
Ask for help if the button vanished for several people at once, the add-in is greyed out, or company policy blocks add-ins.
Menu names can differ slightly between Outlook versions.
