MSTeams Fastconnect Outlook Addin Disabled

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.

1. Launch RegEdit.exe
2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins
3. Verify TeamsAddin.FastConnect exists.
4. Within TeamsAddin.FastConnect, verify LoadBehavior exists and is set to 3.
5. If LoadBehavior has a value other than 3, change it to 3 and restart Outlook.

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

1. Launch RegEdit.exe
2. Go to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Resiliency
3. Delete the DisabledItem if there is.
