To have Microsoft Teams open links in your default browser instead of Edge, you need to adjust the settings within Teams. Go to Settings > Files and links > Link open preference and select your preferred browser from the dropdown menu. This setting will override the default behavior of Teams opening links in Edge.

1. Open Teams Settings: Click on your profile picture in Teams and then select "Settings".
2. Navigate to Files and links: In the Settings menu, locate and click on "Files and links".
3. Change Link Open Preference: Under "Files and links", you'll find "Link open preference". Click the dropdown menu and choose your desired browser.
4. Apply the Change: The change should be applied automatically, and Teams will now open links in your chosen default browser.
