Hi
My name is Daniel. I am an Independent Advisor.
You can stop the MS Team app from opening automatically.
Please follow these steps:
1. Open Task Manager and select Startup tap, then select Microsoft Teams and Disable its startup process.
2. Go to Microsoft Teams app, click profile pic icon > Settings > General, then clear the check box next to “Auto-start application”.
