Why are my files not syncing properly in Teams?

1. Check your internet connection and whether any settings have recently changed.
2. Ensure the latest version of Teams is installed, as well as any necessary updates.
3. Check the size of the file you're attempting to sync. If it falls above the Teams-recommended size limit (15GB) you'll need to reduce the file size.
4. Verify that the file is not being blocked by your corporate firewall.
5. Refresh the settings for Teams on your device by logging out and back in.
6. If the issue persists, consult Microsoft's support page for further instructions.
