Microsoft is investigating a known issue affecting Outlook for Microsoft 365 users and preventing them from creating Teams meetings using the app's ribbon menu.
The Teams Meeting add-in, as its name says, can be found in the Calendar view and it enables Outlook users to schedule a Teams meeting from Outlook.
Redmond's acknowledgment comes after customer reports who described experiencing this issue have been pouring on various online platforms, from Reddit to Microsoft's community website, for the last couple of years.
This issue occurs because the Teams Meeting add-in for Outlook becomes disabled, which leads to the meeting creation option being removed from the menu.
"When you attempt to create a Teams meeting in Outlook Desktop you find that the option is missing on the ribbon," Microsoft said in a support article published over the weekend.
While Redmond is still investigating the cause behind this ongoing issue, customers say that the add-in is likely disabled automatically after causing Outlook to crash, and no amount of repairing, uninstalling, and reinstalling the app can help fix this.
"The Outlook and Teams Product Teams are investigating this issue further to determine why the Teams Meeting add-in is being disabled," Microsoft said. "We will update this topic when we know the final resolution."
Workaround available
The company also shared a workaround to allow customers experiencing issues with this Outlook add-in, which requires users to manually turn the add-in back on and add a registry key to prevent it from being auto-disabled again.
The toggle on the Teams Meeting add-in from Outlook, you need to go through the following steps:
-
In Outlook select File > Options > Add-ins > Manage, select “Disabled items”, and then Go.
-
If you see Teams listed under Disabled Items select it, and then select Enable.
-
Restart Outlook and confirm if the add-in is working.
To block Outlook from disabling the add-in again, you have to add a new registry key:
- Open Registry editor
- Go to Registry Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Resiliency\DoNotDisableAddinList
- Create a new DWORD (32-bit) value:
-
Name: TeamsAddin.FastConnect
- Value: 1

Confimed. This is happennig for us often. But I cannot confirm, that it disables when outlook crashes. By my experience, if loading the plugin takes more than second or so, the addin is disabled and you have to re-enable, or create the registry setting.
Warning, rant incoming: Oh we are so glad, that we have fifth new O365 UI, while the functionality is the same and the fundament (Office settings dialog) is the same from Office 2010! The problem is sitting there "for the last couple of years" as written in the article. I would rather have functional Outlook and Teams, then useless window header image changing option or other cosmetical changes.

Been fixing this issue for years when I worked in IT Support, comes up after a windows update.

We've recently had this issue where Teams addin disappears and seemed to be happening on older laptop stock.
After investigating we found for us it was due to the affected laptops not having .net 4.8 installed.
Once installed the plugin started to work again.

This process worked for me. I don't have the ability to edit registries on my work computer. I will mention though that it tried to disable it again a few minutes after I fixed it. It's excuse was that it was slowing down the opening of other items.....by 0.58 seconds haha. It did allow me to say not to check for 30 days for efficiency with that application add-on which hopefully at least stops it for 30 days.
