Once I'd done the bulk of the work I found my workplace Outlook 2003 could export .VCF (vCard) files that OS X address book could import. Contacts don't change too often, so I just sorted by Contacts by date revised and emailed the new ones.
Then I went to Outlook 2007, the poor, broken, abused step-child of the Office 2007 suite. Outlook was ugly but serviceable in 2003, but Microsoft butchered it for the 2007 transition. One of the many broken bits was the semi-documented vCard export. In 2007, the only vCard export option is tied to sending them as email attachments.
I could live with that, but in OS X Address Book these Outlook 2007 vCards have notes full of unreadable XML.
So, in desperation, I closed my eyes, tried to ignore my past experiences with Outlook Add-Ins, and tried this product in trial mode ...
I decided that was a strong sign this wasn't a serious product, so I uninstalled it.
I then restarted Outlook 2007 -- and found the Add-In had not been removed and Outlook was revolted by it.
So now Outlook showed the SyncWiz add-in as disabled. Fine, but I'd just as soon delete it forever.
Except, you can't delete an Outlook Plug-In from Outlook 2007. You can only inactivate it, and admire the festering corpse.
I hate Outlook Add-Ins. I ain't well disposed to either Microsoft or Outlook 2007 either ...
