I have tried this as well on my machine but still no luck.  I am connecting to an Exchange 2007 server with form based authentication.  I also have the latest and greatest updates for Evolution.  When I run exchange-connector-setup-2.24, fill out my information and hit forward I get the following error;

** (exchange-connector-setup-2.24:6369): WARNING **: Invalid uri 'owaauth.dll'

** (exchange-connector-setup-2.24:6369): CRITICAL **: e2k_soup_message_new_full: assertion `msg != NULL' failed

Not sure what this means but I can't seem to get by it!  I have tried several different formats of the web address and username and they either don't work or return this error.  Below is the debug information;
