I have a script that goes out and checks each mailbox and gets the DeviceType, DevicePolicyApplied, LastSuccessSync, DeviceUserAgent, and the User for each mailbox on Exchange 2010 that has an Active Sync device. You can find it here: http://blog.powershell.no/2010/09/26/getting-an-overview-of-all-activesync-devices-in-the-exchange-organization
Looking through that CSV file results, I can see A LOT of cleanup that needs to be done. I know users can manage their own devices through Outlook Web, but I can clearly see that is not happening. Some are even getting close to the 10 device limit.
Is there a way, other than going to each mailbox in the management console, to remove stale/old active sync device partnerships that haven't sync'd in a given period of time. 6 months? a year?
I would like to get an accurateread out of the types of devices people are using, but with so many old devices out there, making it hard to do so.
Also, wondering if it's good practice to clean up stale active sync device partnerships. Would be nice if Exchange had a built in automatic way to handle these stale devices.
