Well,
I tried Deja, and it has some problems.
Yes, it found my Outlook files on the internet, and syncronized.
By the way, I set it to be one-way, PC=>770 just to be safe.
What I really needed this for was to put my contact list onto the 770.
And it did so, but the list is kaflooey.
All my contacts are Business, but they listed in a haphazard order, only when listing All as the option. Business Only left nothing listed.
Now, could be the way I entered the contacts, but both my PC outlook and PocketPC Contacts listed them alphabetically.
Deja listed them weirdly, and there is no way to browse by first letter, etc, so you have to scroll through the full list to find them.
Not good.
And when I went to do anything else, the only way to switch between some menus was to hit the X close gadget, and the entire program closed.

Now, I'm happy I have all the contacts on my 770, but this program needs major work if I'm going to pay $10 per month.
