Are you using SOHO? , because I read somewhere there is now a plugin for KMail (read their Forum and website), also for Thunderbird (
http://forums.mozillazine.org/viewtopic.php?p=3041238&), with trespect to getting mail off a MS Exchange Server. That would be a LOT easier than getting all the Gnome libraries installed on your machine and then compiling Evolution for VectorLinux, IMHO...The other way is to talk to your system admins and get them to enable IMAP/POP on the Exchange Server. Apparently that is an easy task...
