  • Hi,

    Sorry for my mistake. Your Exchange server is Exchange 2013, is it right?

    In Exchange 2010, you need to find the Microsoft Exchange System Attendant service on the Mailbox server.

    You mentioned above that you deleted a mailbox database in which the System Attendant mailbox located, but in Exchange 2013, there is no the System Attendant mailbox and the Microsoft Exchange System Attendant service any more, but the object is still present in the configuration partition.

    And from the error message you provided, it seems that this account doesn't have the required permissions: Enterprise Admins, Domain Admins and Organization Management.

    Besides, the error shows the current Active Directory forest is not Windows Server 2003 native or later, it is not supported for Exchange 2013.

    Best regards,
    Belinda

  • Hello,

    Are you referring to a System Mailbox or the System Attendant mailbox?

    Can you please post the result of this command:

    Get-Mailbox -Arbitration | format-table Name, Alias

    ?

    Running the setup.exe /PrepareAD will enable you recreate it (in the event that it has been deleted).

    Regards

  • It was System Attendant Mailbox

    will setup.exe /PrepareAD dismount my databases? Because we have active database and we don't afford downtime.

    Thanks

  • Hi,

    Please check if you can see the System Attendant object in the configuration container, you can find the following location to locate it.

    CN=Microsoft System Attendant,CN=<servername>,CN=Servers,CN=<sitename>,CN=Administrative Groups,CN=<orgname>,CN=Microsoft Exchange,CN=Services,CN=Configuration,CN=<domain>

    If there is, please right click it and choose Properties, under the Attribute Editor tab find the homeMDB attribute. Please change it to a existing database in your environment. Then restart the Microsoft Exchange System Attendant service to check the result.

    Best regards,
    Belinda
