Hi,
I'm getting "Proxy Authentication Error - 2606" when I try to sync my OneDrive. Currently using OneDrive App, however it's difficult to maintain a copy on laptop and then sync. Need to Explorer version on my laptop, which was there initially. Recent PW update started giving me this error.

Thanks

First sign-out of your Microsoft account

Open the command prompt window by pressing Windows + R

type in this command: RunDll32.exe InetCpl.cpl,ResetIEtoDefaults

Run that script without checking the box in the prompt

Re-open outlook/onedrive and sign-in and you should be all-set

This worked for me and my client

    Thank you Dakota this was the fix,

    Not sure why MS has ceased the SARA. You can download it but it deverts you to the useless 'Get Help' app.

    SARA was much better,
