OneDrive on Windows 10: no proxy support


    i just upgraded my laptop to Windows 10, and now the OneDrive client is not working when I'm connected behind the proxy server of my office.

Proxy server settings are correct and working on both browsers: Edge and Internet Explorer.

The proxy server technology is Squid and it runs on a Linux machine.

I use also the OneDrive for Business client, this one works fine (it just takes a little more time to connect).

Can anybody help me?

I posted this same question on, but a Forum Moderator kindly recommended me to try TechNet Forums (

I have tested on my computer:

Set proxy and port in Internet option -> Check the sync things on my OneDrive built-in in Windows 10.

There is no problem on my OneDrive sync.

Would you please let me know if you use the any Firewall or client to set the proxy?

Try to capture the network trace by using Message analyzer to see what was dropped your link of OneDrive.

Hello Kate,

    thanks for your reply.

I set the proxy server setting in Internet Explorer (but works also on Edge and other software).

I use the integrated Windows Firewall and I did NOT change anything since upgrade to Windows 10.

I downloaded and installed Message Analyzer, but I don't know how to use it, is there an easy way to filter only the OneDrive Application?

However, as the problem seems to happen only on OneDrive (not OneDrive for Business) I'm quite sure that the issue is there.

After upgrading to Windows 10 I had several problems with third party software (for example Apple iCloud and Vmware Workstation), but most of them got solved just uninstalling and reinstalling the software.

So I would like to know if there is a way to uninstall and reinstall this component.

Since the OneDrive is the system component now, please try following commands to repair system to make sure this issue is not related to corrupted system files:

Dism /Online /Cleanup-Image /RestoreHealth

SFC /scannow

If the issue still persists, I recommend you to re-connect the Onedrive with Microsoft account to see what's going on.

I'm having the exact same issue. OneDrive only syncs when I'm connected without using a proxy, but ones I'm at the office or start a VPN it stops syncing. Ones I'm back home or drop my VPN, sync is working again. The proxy does allow me to open the OneDrive web pages etc. but it simply doesn't sync. OneDrive for business keeps on working..

Regards, G.
