Outlook keeps disabling Teams add-ins: How to fix

One of the most popular features of Microsoft 365 that makes it such a successful platform in a work office environment is how well integrated all the applications are. The integration of Microsoft Teams and Outlook is an example of this as users can quickly and easily access Microsoft Teams features directly from their Outlook application at the click of a button. 

However, in order for this feature to work, first you must install the Microsoft Teams add-in for Outlook. Once this is done a new icon will appear at the top panel of your Outlook page. Recently, however, people have been reporting errors in this feature as Outlook keeps disabling the Teams add-in and they can’t seem to find the icon that should be on the top panel of the Outlook Home page. In this blog post, I will provide a step by step guide on how this issue can be resolved.

How to fix Outlook when it keeps disabling Teams add-ins:

Method 1: Reinstall Teams

  • Open Run command
  • Type ‘appwiz.cpl’ and click ‘OK’
  • A window for Programs and features will appear
  • Search for Microsoft Teams and click on it
  • Then select ‘Uninstall’
  • Once Teams has uninstalled, restart the system
  • Next, Redownload Microsoft Teams
  • Launch Outlook and check if the Teams add-in is working
  • Enable the Teams add-in in Outlook

Method 2: Enable Teams add-ins in Outlook

  • Open Outlook and click on ‘File’
  • Then select ‘Options’
  • From the Left hand side panel, click on ‘Add-ins’
  • Select ‘Go’
  • Select the box for ‘Microsoft Teams Meeting Add-in for Microsoft Office
  • Click on ‘OK’

A commonly experienced situation with Microsoft Teams is that it can often go through issues resulting in certain files and add-ins not appearing or working properly. Reinstalling Microsoft Teams is a simple but effective way to resolve this issue. Once Microsoft teams has been reinstalled and the add-in is still not working in Outlook, then try enabling the Teams add-in in Outlook. It may be that after reinstalling Microsoft Teams, the add-in unchecked itself from the add-ins in Outlook, therefore it needs to be enabled manually in order to work.
