Sync BB Contacts to Outlook Export to DROID - BlackBerry Forums at CrackBerry.com
Check out this post I made on another forum a while back.
I'm not familiar with Windows mail.... see if there is an option to "export" in menu.... create a .csv (comma seperated values) file of your contacts then just follow the second half of in thread i linked to you.
I'll dig a bit and post back.
Edit: Bingo... Got it here. How to Export Contacts and Email Addresses from Windows Mail - About Email
Edit 2: Here's another just in case How to export e-mail messages from Windows Mail & Outlook Express into Outlook.
