We have finally started syncing today (Monday 3/1) after two full months! Got MS on the phone last Friday, said they needed the weekend to look into the issue and come today, things are working now. Crazy how that works out sometime, so when they called back I told them to check back in 24 hours to make sure it is fixed.
