Update Microsoft Teams
The desktop app automatically updates (so you don’t have to). If you want, you can still check for available updates by selecting the Settings and more menu next to your profile picture at the top right of Teams, and then selecting Check for updates.
The web app is always up to date. It’s just good like that.
Note: Linux users aren't able to update manually within Teams at this time.
To update the Teams mobile app, download and install it again from the iOS App Store or Google Play Store.
