How to remove third-party app access in Outlook Calendar

Published  June 4th, 2021  by Michael Nilsson

When you use any of our add to calendar functionalities, you connect and grant access to our app at Microsoft to insert the event. 

To revoke that access (and that goes for any services you might have granted access to in the past), follow the numbered steps below: 

  1. Head to and sign in to your account
  2. Click on the Privacy tab at the top of the page. You may need to verify your identity via an email code
  3. Scroll down to the Other privacy settings section
  4. Go to Apps and services > Apps and services that can access your data
  5. Review the list of apps and establish which you want to revoke
  6. Click on Edit below the corresponding app's name

  7. Select Remove these permissions
