A Microsoft file hosting and synchronization service.
The best thing I have been able to do is unlink my computer from onedrive. I can leave it that way or partially install onedrive up to the point of installing the personal vault - just leave it hanging. That is how I have it now, I am waiting to see how that works and if it causes me any problems.
Update:
This solution is working for me since August 24, I have OneDrive with no continuous threats to not sync.
