There is no device-to-device option that I'm aware of, however if you're already syncing your data to Outlook, then just re-sync it into the Blackberry using the including Blackberry Desktop Manager version of Intellisync.
On the other hand, if you've been using the Palm Desktop software, and your information is already there, another utility by Chapura (the same folks who make PocketMirror) will convert all
of your Palm Desktop data into Outlook. See http://www.chapura.com/pocketcopy.php
If you're converting over permanently, I find this to be a faster and more reliable method than syncing the Palm data into Outlook via PocketMirror, as it simply directly converts what's already in your Palm Desktop.
