Hi,
I will walk through a few steps with you. Some of these are just to help figure out what is wrong, not to fix it right away. So if nothing changes after a step, that is normal. I will keep going until we solve it.
I will work with you on this issue.
#1: Please go to https://onedrive.live.com and sign in. Go to Files > Desktop. You should see your files.
#2:
Reinstall Onedrive again. Then,
- Click the OneDrive cloud icon in the taskbar (bottom-right corner, near the clock).
- Click the Gear icon (Settings), then select Settings.
- Go to the Sync and backup tab and click Manage backup.
- Toggle on the Desktop, Documents, and Pictures folders.
- Select all the files on the Desktop. Select Always keep on this device.
- You can then safely toggle off Desktop, and the files will remain.
I look forward to hearing from you to get the results of the troubleshooting.
