Teams Meeting Add-in Missing in Outlook? How to Get It Back

You go to schedule a meeting in Outlook and the Teams Meeting button is gone. This usually happens right after Teams updates itself, especially when moving to the new Teams. The update doesn't always install the Outlook add-in correctly, so it disappears from Outlook and from the COM Add-ins list.


Here's how I get it back, starting with the quickest check.



Fix 1: Turn the Add-in Back On in Outlook


Sometimes the add-in is installed but Outlook turned it off, often because it was slow to load.


  1. In Outlook, go to File > Options > Add-ins.

  2. At the bottom, next to Manage, choose COM Add-ins and click Go.

  3. Tick Microsoft Teams Meeting Add-in for Microsoft Office and click OK.

  4. If it isn't in the list, set Manage to Disabled Items, click Go, and enable it from there.


Restart Outlook. If the button is back, you're done.



Fix 2: Reinstall the Add-in


If the add-in is missing completely, have Teams install it again.


  1. Right-click the Start button and choose Settings > Apps > Installed apps.

  2. Search for Teams Meeting Add-in, click the three dots and choose Uninstall.

  1. Close Outlook.

  2. Fully close Teams: right-click the Teams icon in the system tray (near the clock) and choose Quit.

  1. Open Teams again. It reinstalls the add-in in the background, which can take a few minutes.

  2. When Teams Meeting Add-in shows up in Installed apps again, open Outlook. The Teams Meeting button should be back.


Note: on a work computer, reinstalling the add-in may need administrator rights. If it doesn't come back, your IT department may need to reinstall it.



Fix 3: Check the Registry Setting


If the add-in keeps turning itself off, check how Outlook is set to load it. Close Outlook, open regedit and go to:


HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins\TeamsAddin.FastConnect

Double-click LoadBehavior and make sure it's set to 3. That tells Outlook to load the add-in every time it starts. Then open Outlook again.



Using the New Outlook?


The new Outlook for Windows doesn't use this add-in. Teams meetings are built in. When you create an event, turn on the Teams meeting toggle. If you don't see it, check that you're signed in with your work or school account.



Still Stuck?


If the Teams Meeting button still won't show up, IT-Tech can connect remotely and get it working again.
