BES Express install for dummies like me with Exchange/SBS2003
 

I have a SBS2003 server that I'm trying to install BESx on. For now, there will only be one user.

What I'm trying to figure out is how I connect my Alltel 8830 to the BESx. I want to sync my calendar and email.

How do I associate my PIN with Exchange and the BESx? Many years ago I used BES with Domino and remember seeing a place to add PIN numbers but I don't see that with this version.

I have Windows Vista on my laptop and downloaded the latest desktop software.

You don't need to use your Vista desktop at all and you don't need your PIN number to get started on BES.
