When looking at ActiveSync phone devices, I see a phone number for Android devices but not for iPhone's. Is there something that I need to enable to retrieve the phone number of a iPhone or any ActiveSync device? Thanks Ron

It all depends if the device reports it or not. There are many differences between clients in that regard: http://en.wikipedia.org/wiki/Comparison_of_Exchange_ActiveSync_clients

Thanks The table didn't list the devicephonenumber attribute. It looks like Apple doesn't provide the phone number to ActiveSync/AD. Ron
