I tried everything above - found the office option under telephone. Re- paired the phone. No "current office" appeared. Then I realized that when I re-paired the 4s, Apple defaults back to no notification. Swithed it on - didn't work. Up paired the phone than tried every iteration possible and couldn't find the Office option under telephone again. I had also turned off MMS on the phone as well. Rechecked that the software was updated etc,etc. Gave up! Then I come back three hours later and there was the Current Office TAB.
I just can't figure out this car.
None the less - thanks for the help on this thread for helping me get this far!
