Hi. We are using Lync 2013 clients on Nokia Windows Mobile 8 phones. Works great except that the client closes when the user presses the phone's "back button'. I realise this is generally normal behaviour for mobile apps. However it would be very useful if the client remained active and could only be exited through a menu option (as opposed to the back button). The problem with the back button is that it is too easy to hit and therefore too easy to close the Lync client, without warning.
Is there a upgrade to the Lync client available to solve this problem. We are currently using ver 5.2.1072.0.
