My One Drive App No Longer Accessible

Topic

New Reply

MS auto updated my computer (64 bit Win 10 1809) this morning and rebooted my computer. Gone from the system tray is my Office 365 One Drive app. Attempts to connect to One Drive from the Start menu result in nothing happening. The computer can not access my One Drive at all. I even tried using the web (Edge no less) and when I try to enter my email address, half way through, the dialog box blanks out.

I can find no help or information using MS help.

Any suggestions or information appreciated.

Can you please verify the KB number of the update you received and the Win10 1809 Build number?

The “Update” is listed as a Feature Update for Win 10 1809 but no KB number given. The build is 17763.316.

I have now been able to access my One Drive account by using the web with the address onedrive.live.com, but this does not really solve the problem which is the loss of the automatic file backup feature which stores copies of my documents.

It was a feature update, not a cumulative update. They don’t have KB numbers.

Yep, that page lists cumulative updates for that version:

Updates for Windows 10, version 1809

On the left side of this page, you’ll find a list of all the updates released for this version of Windows.

Build 17763.1 is not listed there because it was a feature update.

 

A feature update does not have an associated KB:

Finally, after several runarounds and attempts find the right place to ask, I was able to connect with a Microsoft One Drive Support person. Said I should download a One Drive installer. Did, and it did not work. Then told to run a reset procedure. Did not work.

Then the big gun was brought out. I was instructed to edit the registry to change One Drive’s DisableFileSyncNGSC  from 1 to 0. This would, and did(!) “enable” One Drive after restarting the computer. All is now as it should be. I have no idea how this bit (Dword actually) got changed. Hit by a cosmic ray is as good an explanation as any.

If there is interest in the registry edit I can post the full navigation from HKey down, but it is lengthy so I omitted it here.

It’s OneDrive’s integration switch at:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\OneDrive

You can change the DWORD value for DisableFileSyncNGSC from 1 to 0 to re-enable OneDrive integration or just delete the DisableFileSyncNGSC entry entirely.

A .REG file to make the change looks like this:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\OneDrive]
"DisableFileSyncNGSC"=-

Just restart Windows (or use gpupdate /force from a Run dialog [WIN key +r]) for the change to take effect. Following the change you should then be able to log back into OneDrive.

Hope this helps…
