Successfully using MobileMe behind a proxy server at work on a pc or a mac

I have had problems with this as well and the only way I was able to solve this issue successfully was to use a program that allows network applications that do not support working through proxy servers to operate through a HTTP HTTPS or SOCKS proxy server or a chain of proxy servers.

Proxifier

Now I had some issues getting it going but with the help from the people at Proxifier I was able to solve these and get it going.

Essentially you MUST completely disable the proxy settings in
System Preferences > Network > Advanced > Proxies.

Then you set up Proxifier to forward all communication from your applications.

then you set up rules on what and how you want proxifier to handle either everything or only the applications you specify.

Now I suggested the people at Proxifier update their online documentation to include an article on how to get MobileMe going from behind a proxy with Proxifier which they have decided to do.

It just works easily once you have it set up I recomend you have a go at it and I think you will be happy with the solution.
