Have you tried searching for this error on Google? I did a search under "Proxy Authentication Required" and "Remoting" and it turned up a ton of entries. You could probably search through those threads to see if they have a solution that helps you.
Hi johnny,
Thanks a lot for replying
sourcecode, did you ever find a solution for this as I am running into the same issue now when connecting to an Exchange Server, I'm going to make a separate post about it, my error message is:
61012 Exception from message source myemail@domain.com: System.Net.WebException: The remote server returned an error: (407) Proxy Authentication Required.
