A Microsoft file hosting and synchronization service.
I found a fix!
Switch to DROPBOX.
I am so disappointed in Microsoft's technical support. This issue has been going on for months and is unacceptable.
If enough people switch to another cloud-based company, they may get the hint.
So far DROPBOX seems more stable, quicker, and has better support. $10/m gets you 2TB of storage with more features than Onedrive.
Good luck everyone!
