Most Teams clients are updated automatically by Microsoft on a daily basis. However, if you need to manually update your Teams desktop application, do the following:

1. Open the Teams desktop application on your computer.
2. Click on the three-dot More options menu to the left of your user icon.
   

    
3. Select Check for updates. A grey bar will appear at the top of your client that indicates Teams is checking for updates.
   

    
4. When this bar disappears, exit Teams completely and re-launch it to complete the installation of any updates.

Note: In some older versions of Teams the Check for updates option can be found in the menu accessed by clicking on your user icon.
