Hi Ty_159,
Thank you for reaching out. My name is Furkaan, a user just like you. I’d be happy to help you with your concerns. It sounds like you've done a good amount of troubleshooting already for this error accessing "My Files" and "Favourites" in Teams. Here are some additional steps you can try to fix the issue, considering it's happening on both the desktop app and Teams Online:
Check Microsoft 365 Service Status:
Visit the Microsoft 365 Service Status page (https://learn.microsoft.com/en-us/microsoft-365/enterprise/view-service-health?view=o365-worldwide) and check for any ongoing issues with OneDrive or Teams. If there's an outage, you'll need to wait for Microsoft to resolve it.
Network Connectivity:
Make sure your internet connection is stable. Try using a different network, if possible, to see if the issue persists.
Temporary Profile:
Create a temporary user profile on your computer and test accessing Teams in it. This helps isolate if the issue is with your current user profile. Check Teams Version and Updates:
Ensure you're running the latest version of the Teams desktop app. Update it manually if necessary (refer to Microsoft documentation for update instructions).
Advanced Troubleshooting:
Microsoft Teams (Desktop App):
Try running Teams in compatibility mode for an older version of Windows. If comfortable, consider a registry edit (with caution) as suggested in some forums. However, proceed with this only if you understand the risks and with proper backups in place. Teams Online:
Try using a different web browser (e.g., Chrome if using Edge) and ensure it's updated. Consider temporarily disabling any browser extensions that might interfere with Teams functionalities.
Contact Microsoft Support:
If none of the above solutions work, it might be best to reach out to Microsoft Support for further assistance. They might have access to more specific tools and resources to diagnose the issue based on your account details.
