There are some dependencies which have not been properly encoded into the Exchange MAPI plugin for Evolution in Ubuntu 13.04. To get MAPI support, you must install: evolution-mapi and python-samba.
I was not able to get Exchange MAPI to work with Drexel's Exchange server: the issue was during the authentication step. However, using Exchange Web Services works. This uses Exchange's web service, which presents all the data in XML. To use this, the evolution-ews package has to be installed. Then, for the Host URL, use the usual web access address, appended with /EWS/Exchange.asmx So, if the webmail address is https://exchangeweb.myorganization.com/ the Host URL for Evolution will be https://exchangeweb.myorganization.com/EWS/Exchange.asmx
UPDATE: There is a bug in the exchange-ews package: there is an issue with sending mail. To fix, edit the the file in ~/.config/
