Account for Exchange ActiveSync service

April 17, 2024

ID 92340

When an Exchange Mobile Device Server is installed, an account is automatically created in Active Directory:

  • On Microsoft Exchange Server (2010, 2013): KLMDM4ExchAdmin***** account with the KLMDM Role Group role.
  • On Microsoft Exchange Server (2007): KLMDM4ExchAdmin***** account, a member of the KLMDM Secure Group security group.

The Exchange Mobile Device Server service runs under this account.

If you want to cancel the automatic generation of an account, you need to create a custom one with the following rights:

  • When using Microsoft Exchange Server (2010, 2013), the account must be assigned a role that has been allowed to execute the following cmdlets:
    • Get-CASMailbox
    • Set-CASMailbox
    • Remove-ActiveSyncDevice
    • Clear-ActiveSyncDevice
    • Get-ActiveSyncDeviceStatistics
    • Get-AcceptedDomain
    • Set-AdServerSettings
    • Get-ActiveSyncMailboxPolicy
    • New-ActiveSyncMailboxPolicy
    • Set-ActiveSyncMailboxPolicy
    • Remove-ActiveSyncMailboxPolicy
  • When using a Microsoft Exchange Server (2007), the account must be granted the access rights to Active Directory objects (see the table below).
