Distributing apps for Windows 8.1 Phone devices

This section describes the certificates and tokens required for distributing in-house apps for Windows Phone (8.1) devices only.

After registration, the Windows Phone device is in Verified state. The device state changes to Active after the device checks in with Ivanti EPMM for the first time. This may take approximately ten seconds and up to one minute after registration. If the device user logs into the Apps@Work app before the device changes to Active state, the user will not be able to sign into Apps@Work because Ivanti EPMM is not yet associated with the device.
