Running in to an issue after an Exchange ActiveSync device is removed using the “Remove-ActiveSyncDevice” PowerShell command.
We successfully removed over 1200 out-of-date devices from Exchange ActiveSync.
After removing all devices, the issue is with 160 mobile devices that are reporting back to as what I’m referring to as ‘unassigned’.
The user is still able to send and receive emails from their mobile device, but the device does not show up in the EMC or ADSI under the user. When exporting ALL_Domains using the “Get-ActiveSyncDevice” without specifying the -DomainController the “UserDisplayName” is empty and the “DistinguishedName” is showing the same as ADSI Configuration Naming path listed below.
With 1 test user, we removed the Exchange account from the mobile device, rebooted the device and then added the Exchange account back to the mobile device. Now the device shows up under ADSI assigned to the user, but not in the EMC.
When changing ADSI to Configuration Naming Context for the parent domain, the unassigned mobile devices are reporting back to
“CN=<***device name***>,CN=ExchangeDeviceClasses,CN=Mobile Mailbox Settings,CN=<*******>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=<*******>,DC=net”
Ran the following commands
- Set-ADServerSettings -ViewEntireForest $true
- Exported the “Get-ActiveSyncDevice” for each of our domains, 1 parent and 3 child domains
- Get-ActiveSyncDevice –domaincontroller dc.child.parent.net | export-csv .\child_Domain_vDate_Time.csv
- Remove-ActiveSyncDevice -Identity <GUID ********> -confirm:$False
- Get-ActiveSyncDevice | export-csv .\ALL_Domains_vDate_Time.csv
- This command without specifying the Domain Controller is reporting back the empty “UserDisplayName”
