Microsoft Teams is a collaboration and chat software that offers a wide range of features. Microsoft wants its users to be productive and be able to switch from one product to another. And integration with Outlook is one of those features. Outlook has a simple button that allows users to connect directly to Microsoft Teams. However, some of our users have reported that they can’t find this button. So, if you are one of those users who is having trouble connecting Teams to Outlook, this article is for you.

Microsoft allows its users to open Teams in Outlook to access the mail client. In this way, the work becomes more efficient and more complex. It also has the advantage of having everything in one place. So, if you are having trouble linking teams in Outlook, follow this guide carefully and you will soon be able to do so. So, let’s get started.

What are the reasons for the missing Microsoft Teams add-in for 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.
  • Outdated Office: The user may be running an old, incompatible version of Office.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.
  • 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 Deployment does not currently 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.
