Requirement checklist

    Note: %os_username% is the username of the operating system account for backup.

  • Membership setting of the operating system account
    The Active Directory account used for the backup must be a member of the following security groups:

    • Microsoft Exchange Security \ Organization Management
    • Users \ Administrator
    • Users \ Domain Admins
    • Users \ Enterprise Admins

  • Remote Exchange Management Shell
    Remote Exchange Management Shell must be enabled for the operating system account used for the backup. To do that, enter the following command in Exchange Management Powershell:

    >Set-User "%os_username%" -RemotePowerShellEnabled $True

  • Mailbox enabled
    The Active Directory account used for the backup must be have one or more Exchange Server mailboxes associated with it.

    Download and install CDO with the following installer: ... x?id=42040

  • LAN Manager authentication level
    The LAN Manager authentication level configured on the Exchange server must be level 3 or above. To check on the setting:

    • Open Local Security Policy from Administrative Tools.

    • Under Security Settings, expand Local Policies, Security Options, Network security: LAN Manager authentication level.

    • Ensure that the setting is configured to use NTLMv2, for example:

      • Send NTLMv2 response only
      • Send NTLMv2 response only. Refuse LM
      • Send NTLMv2 response only. Refuse LM & NTLM

  • .NET Framework 3.5 Features
