Outlook Calendar - Teams Meeting Missing From Ribbon

Notes

Outlook monitors add-ins and how much impact they have on Outlook startup times. Outlook will disable any add-ins it feels are causing excessive delays, which frequently includes the Microsoft Teams Add-in.

This procedure shows how to re-enable the Teams Meeting Add-in so that Teams meetings can be scheduled from the Outlook Calendar.

Procedure

Below is a screenshot of how the Outlook Calendar ribbon will appear when the Teams Meeting Add-in has been disabled
2. This issue is most commonly caused when Outlook has disabled the add-in because of its impact on Outlook's startup process
To resolve the issue, first click File from the top left of Outlook
Now look for the extremely obvious yellow-highlighted "Slow and Disabled COM Add-ins" section
Click the "Manage COM Add-ins" button to access the settings
Expand the "Options" listed under Microsoft Teams Meeting Add-in for Microsoft Office, then choose "Do not monitor this add-in for the next 30 days" and click Apply
Restart Outlook and the Teams Meeting Add-in should be returned to its rightful place
