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!

Hi Leo,

You can use the following commands mentioned in the referenced article below

Get-ActiveSyncDevice

Remove-ActiveSyncDevice

Article: How to Manage Mobile Devices by Using Configuration Manager and Exchange

Get-MobileDevice returns nothing

But the Control shows three devices

I think I need to find a way to delete them manually...
