connect to exchange 2007 mailbox and alert unread and total recieved for day

I am a bit stumped how to do this.   I have found a script that works on exchange 2003 but not 2007.  Anyone have any idea how to make this work or other suggestions.  I saw some ews soap code but it was a bit much for me to understand.  In our enviornment we use owa as follows.   https://owa.externalDomainname.com/owa.      I am hoping some url password auth is all the script needs.  OWA does not allow passthru and is in form based mode.  Thanks for any suggestions.  My goal is to detect all unread emails and total meeting current date for the day if possible.  getting into owa is the big step though. It appears to be a login time out probably due to forms based.
