Personal tabs provide a great way to enhance the Microsoft Teams experience. Using personal tabs, you can provide a user access to their application right within Teams, without the user having to leave the experience or sign in again.

You can build and run your personal tabs in Teams, both Outlook desktop and web experiences, and also the Microsoft 365 app on the web.
