Query exchange server 2010 (or 2007)

Hello,
 
I need help to query exchange server (get mail box details etc...) using a (any) programming language. I need to create an application which gives the values for different exchange server parameters (like mailbox size). I have already created a C# (with power-shell) sample for this and that is not working from a remote machine. Any help on this would be greatly appreciated.
 
Regards
Sebastian
