Re-enabling the Teams Add-In for Outlook

The purpose of this article is for when the Teams Meeting add-in has seemingly disappeared when trying to include a Teams meeting within an Outlook appointment. 

The common cause of this is that the Teams Add-In caused Outlook to crash and so Outlook has automatically disabled it. To check if this is the case, within Outlook navigate to File --> Options --> Add-ins. You can quickly tell if this add-in is inactive as it will be in the Inactive/Disabled Add-ins rather than Active

If Disabled, change the bottom dropdown menu to Disabled Items & then click Go...

You would then see the Teams add-in in this menu. Click on it, click Enable and then close out of that. You may still need to follow the next step

If Inactive, keep COM Add-ins selected in the bottom dropdown menu and then click Go...

Within the tick menu list that appears you may then have the Microsoft Teams Add-in unticked. Simply tick this and press OK

At this point you will need to fully restart Outlook for this to take effect. To do this, open up Task Manager (Ctrl + Shift + Esc simultaneously) and in the bar at the top search for Outlook. Click on this and then select End task

Once closed, re-open the app and the option to add a Teams meeting to a calendar invite should return
