Hello ivory
Thank you for the detailed information.
Since Teams, OneDrive, and SharePoint work on your Chromebook, your school account appears to be working correctly. The issue is likely specific to your main computer.
Please try:
- Using a different browser (Edge, Chrome, or Firefox).
- Disabling any VPN, proxy, security software, or browser extensions temporarily.
- Clearing your browser cache and cookies.
- Signing out of all Microsoft accounts and signing back in with only your school account.
The "unsupported protocol" and Teams offline mode messages suggest a browser or network issue on the affected device.
If the problem continues, contact your school's IT administrator and share screenshots of the errors. As a workaround, you can download your files from OneDrive on your Chromebook and transfer them to your main computer using a USB drive or local download.
