It seems correct that the exchange contacts (but not all) are the problem. I went through my contacts and selected a bunch of them and added them to favorites.

Then on the iPhone, set it to synch only favorites, and now I have my contacts back and selectable through Bluetooth. However, it only shows my favorites.

I can probably add them one at a time and test to find out which contact(s) are the problem. But that will take a lot of time.

I'm just happy I can dial from iDrive contacts again!
