RPC Proxy Authentication Setting

This policy setting determines the RPC proxy authentication setting for Outlook Anywhere.

If you enable this policy setting, you can specify the proxy authentication setting that Outlook uses, and this overrides any proxy authentication setting specified in Autodiscover.

If you do not configure this policy setting Outlook uses the proxy server authentication specified in Autodiscover.

Supported on: At least Windows 7
