Outlook keeps disabling the MSTeams Fastconnect addin which removes Teams meeting functionality from the Outlook Calendar view. To restore this, I used the following steps.
- Launch RegEdit.exe
- Navigate to
HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins
- Verify TeamsAddin.FastConnect exists.
- Within TeamsAddin.FastConnect, verify LoadBehavior exists and is set to
3
. - If LoadBehavior has a value other than
3
, change it to3
and restart Outlook.

If the add-in has been disabled, you can try to follow these steps to prevent it:

- Delete the
DisabledItem
if there is.
