Here are the three Teams file experience options you have: If you don’t make any changes to your default settings in Teams, documents will open in Teams automatically. If you’re still not seeing it, make sure you have updated to the latest version of Teams.
Note: You must use the desktop version of Teams to enable this feature (doesn’t apply to web version). However, when dealing with complex files you may wish to change how files are opened to be able to utilize the full functionality of the desktop app instead.
You can open files directly within Teams to have a single context in which you’re able to do your work.
