We got a customer that after syncronizing with Exchange 2010 Standard can't connect to bluetooth devices. (Headset and printer.) When he configures the exchange account on his phone he is getting a security warning about certain settings that has to be activated to allow mail sync. After restart of the phone, connection to Bluetooth devices is impossible.
I have checked the ActiveSync Policy on the Exchange server and as far as I can see there are no limitations. And also it looks that Enterprise license is required to restrict anything.
It looks that Adroid devices don't got this problem.
