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

    I'm getting "Proxy Authentication Error - 2606" when logging in to TEAMS as either existing or new user. Stupid TEAMS says I'm disconnected, but I'm online. it was all working fine 5 minutes before I made the mistake of logging off.

    running this had no effect: RunDll32.exe InetCpl.cpl,ResetIEtoDefaults
