Teams Meeting Add-in Disabled by Outlook

Are you suddenly unable to create a Teams meeting in Outlook? You no longer have the option to create a new Teams meeting in Calendar view? You’re not alone!

The general issue in play has long affected Outlook – At launch of Outlook you’re notified that Add-in XYZ is too slow, do you want to disable it? The Add-in in question took all of a half second to load but there’s red text on the screen. Sounds bad, better do that – I need to read email and go to meetings! Only later to realize later that you can no longer do ABC or XYZ. Hmmm, maybe you should have fully read that dialog (that no other app on the planet uses). Now it’s time to click around Outlook madly searching for your beloved Add-in that no longer works. Search the web, reboot (twice!), close and re-open Outlook 4 times… They let you disable the Add-in with a pop-up that you must interact with, but give zero clues how to re-enable it once you realize what you’ve done.  Getting desperate – better open a ticket, or call IT and blame patches demanding a rollback. C’mon, didn’t you know it’s a COM Add-in!? This time wasting cycle has been going on since, well… Outlook.

But! The current issue with Teams that started in early 2023 is bit different – Outlook isn’t detecting “slow” Add-ins and prompting you asking what to do. The current issue with Teams appears to happen randomly with no warnings or prompts, and only to Microsoft’s own Add-in for Microsoft Teams. Want to scheduled a meeting? Ha-Ha! not gonna happen.

The issue: You can’t create a Microsoft Teams meeting. Because… Microsoft Outlook has disabled Microsoft Teams due to “performance” issues.
