Android 5.0 Changing Device ID for EAS

[wpizzi]

I had a user update their Nexus 10 to Android 5.0 and once the update was complete their device was quarantined by Exchange. After looking into the issue the device ID changed with the update. Both OS version are using the same EAS client 2.0 and the runspaceID is the same. Just wondering if anyone else has run into this issue?

Exactly same thing happened to me.
Previews and the OTA and the full factory image all changed my device ID to something different.
I explained to my IT dept if they look the IMEI is the same and it's the same device.
