How to Resolve Missing Microsoft Teams Add-in in Outlook in Windows PC

One of the amazing features of Office is the Add-Ins feature, which makes it easy to switch between applications. We find this especially useful when we want to schedule Teams meetings in Outlook, but recently several users have reported that they can’t find the Microsoft Teams add-in for Outlook on Windows 10.

If you’ve encountered a problem like this, you’ve come to the right place, because in this guide, we’ve listed some of the most effective ways to solve it.

Why is the Microsoft Teams add-in missing in Outlook?

Authentication Requirements: To use the Teams Meeting add-in for Outlook, you must log in to Teams using modern authentication. This is Microsoft’s preferred term for what most other programs call multi-factor authentication.

Nested groups: add-ons will no longer appear to the user if the user is removed from the group to which the add-on is assigned. Centralized provisioning currently does not support nested group assignments. It supports users in top-level groups or groups without parent groups, but not users in nested groups or groups with parent groups.

Outdated Office: The user may be running an older, incompatible version of Office. The user must have Office ProPlus or Microsoft 365 to deploy the add-ons. You can check this manually by opening an application, such as Word, and then selecting File -> Account. Under Product Information, you should see Microsoft 365 Apps for Business.
