Exchange 2010 – The ActiveSyncDevice identity cannot be found

Why not mention Exchange 2010 bug – The ActiveSyncDevice identity cannot be found.


  • The user has a Microsoft Exchange ActiveSync partnership that works as expected.
  • You move the user to a new organizational unit (OU) or rename a user account in Active Directory Domain Services (AD DS).
  • You try to perform a remote wipe operation for the device in the Exchange Management Console (EMC).

Get-ActiveSyncDevice -Mailbox 00164 | select UserDisplayName,Identity 

UserDisplayName : liintra.intra/Users/00164
Identity : liintra.intra/Users2/00164/ExchangeActiveSyncDevices/NokiaEmail§IMiEI284675044284679

Affected objects can be found and reported (csv):

[PS] C:\>Get-ActiveSyncDevice -ResultSize unlimited | sort -Property Identity -Unique | select Identity,UserDisplayName | ? {$_.Identity -notmatch $_.UserDisplayName} | select UserDisplayName,Identity  | Export-Csv -Delimiter "," -Encoding unicode -Path "C:\Users\filip\Desktop\Report170413.txt"


  • Remove-ActiveSyncDevice –Identity “new path = Identity from Get-ActiveSyncDevice“
Remove-ActiveSyncDevice -Identity "liintra.intra/Users2/00164/ExchangeActiveSyncDevices/NokiaEmail§IMiEI284675044284679"
  • During the next mail sync user’s device will perform full sync automatically, but the sync will take longer than usually.
