When a user's mobile phone is configured to connect to Exchange 2013 they get a quarantined email. When I look up the user in EMC it shows the users mobile phone but when I go allow the device I get an error that the device ID can't be found. When I use the Get-MobileDevice -mailbox command for the user it doesn't list anything, but Get-MobileDeviceStatistics -mailbox lists the users mobile device with a DeviceAccessState of Quarantined.
Why does the EMC see the mobile device, but EMS does not? After adding a user's phone I usually wait an hour or two and come back to it, and then the EMS will show the quarantined device. EMS used to show the quarantined device right away but at some point it stopped working that way.
