After upgrading to Exchange 2013 one user had problems connecting a new phone because he was over the limit of (14 I think) devices to connect.
However there were only 3 showing up in the Active Sinc Mobile Device Management and deleting these was not possible.
I deleted all his Mobile Devices with ADSIE that were listed under his user account. I suppose he will be able to connect new devices.
However the 3 Mobile Devices are still showing up in Exchange. I there any way to delete them? Where does Exchange store these information?
Thanks for your help!
