Hi CBW. I'm Greg, 10 years awarded Windows MVP, here to help you.
I'll give you everything possible for fixing Phone app. Even if you've tried a step please try it over in sequence here:
- First try resetting the App in Settings > Apps > Apps & Features > Phone Link (or Your Phone) > Advanced Options > Repair and then Reset. Restart PC.
- Next try re-registering the app from Option 2 here: http://www.tenforums.com/tutorials/3175-apps-re...
