What is OneDrive Proxy Authentication Error 2606?
This error occurs when OneDrive can't authenticate your account through your company's or school's proxy server. It means OneDrive is having trouble verifying your identity, preventing it from syncing files.
Why does this error only happen sometimes?
The error might be intermittent due to temporary network issues, proxy server problems, or changes in your network configuration. Your proxy server might be experiencing temporary outages or require re-authentication.

Sometimes, a complete OneDrive reinstall might be necessary.
