A Microsoft file hosting and synchronization service.
Regarding remote access, I cannot connect to your computer through this forum. Microsoft Q&A contributors do not have remote-access capability. That would be something you need to check with Support Agents.
Please close any file that is still open, wait until OneDrive again reports “Up to date,” and then perform the following:
- Click the OneDrive cloud icon beside the clock.
- Select Help & Settings > Settings > Account.
- Select Unlink this PC, and confirm.
- Sign in again with the same Microsoft account.
- When informed that a OneDrive folder already exists, select Use this folder.
- Allow OneDrive to rebuild the folder statuses completely, and then restart the computer.
