Use the Shell to re-create the Discovery system mailbox

Use the Shell to re-create the Discovery system mailbox


  1. Delete the SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9} user account from Active Directory, if it exists. By default, Exchange Server 2013 Setup creates the mailbox in the Users container in Active Directory. For details about how to delete a user account from Active Directory, see Delete a User Account.
  2. Prepare Active Directory by running Microsoft Exchange 2013 (same for Exchange 2010) Setup with the /PrepareAD switch in the root domain of your Active Directory forest. For details, see Prepare Active Directory and Domains. (go to Exchange installation directory then run  setup /p)
  3. Use the Shell to enable the Discovery system mailbox.
    noteNote:
    You can’t use the EAC to enable the Discovery system mailbox.

    This example enables the Discovery system mailbox. You must specify the fully qualified domain name (FQDN) of a global catalog server in the root domain of the Active Directory forest.

    Enable-Mailbox -Arbitration -DomainController <FQDN of root global catalog server> -Identity "SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}"
    Example:

    Enable-Mailbox -Arbitration -DomainController ADVEXCH.mydomain.com -Identity “SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}”

     

    To resolve this issue, run the following command from the Exchange Management Shell:

    Get-Mailbox -Arbitration and check the validity of the System MailboxSystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}  SystemMailbox{1f05a927-af78-475a-aba4-fc281398eb54}  FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042  DiscoverySearchMailbox{D919BA05-46A6-415f-80AD-7E09334BB852}
    In this case, two system mailboxes were corrupted:
    SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}  SystemMailbox{1f05a927-af78-475a-aba4-fc281398eb54}
    So from the ADSIEdit.msc , Domain Naming contextUsers , user deleted the System mailbox and recreated using Setup/ADprep command (Exchange setup).
    After creating, System mailbox, user needs to enable them. Below is the command to enable them:
    Enable-Mailbox -Arbitration -Identity “FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042”    Enable-Mailbox -Arbitration -Identity “SystemMailbox{1f05a927-8668-4003-adad-9b80758e86db}”    Enable-Mailbox -Arbitration -Identity “SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}”    Enable-Mailbox -Discovery “DiscoverySearchMailbox {D919BA05-46A6-415f-80AD-7E09334BB852}”
    And finally, run the following command to set the display name for one System Mailbox and quota for FederatedEmail:
    Set-Mailbox -Arbitration -Identity “SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}” -DisplayName “Microsoft Exchange”  Set-Mailbox -Arbitration -Identity “FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042” -ProhibitSendQuota 1MB
