I just reinstalled Windows 10 couple days ago. OneDrive stops working completely after every reboot.

1. Onedrive Sync Pending

Onedrive Sync Pending

The service icon for OneDrive sync even disappears. I go into Task Manager, the OneDrive service is dead. In file manager, the OneDrive folder iconlooks just like a regular folder because there is no syncing. I reinstall OneDrive and it works for that session. But, when I reboot, OneDrive again stops working, service does not start-OneDrive dead. I have reinstalled OneDrive 3 times already. Howcan I fix this issue?

I had the exact same issue. Resetting will not help the problem. You are right in that even onedrive.exe goes away.I had to get a new copy and start again. Everything worked (after synching for hours) until the reboot.

This happened on more than 1 PC.See if you have Acronis 2018 with active protection turned on. I noticed that after a reboot I saw the one drive icon for a few seconds and then it and the onedrive.exe was wiped out on my pc. I suspect that the active protection is the problem. I haveshut mine off and so far the onedrive.exe and the process is still working. Let me know what you find out.
