I don’t know how the history, but my task is to re-create all Arbitration mailbox that no longer exists.

The first step is to run .\setup.com /prepareAD


After that you will find 4 user in ADUC that have disabled status, you have to copy all the GUID, mine is like this:

  • DiscoverySearchMailbox {D919BA05-46A6-415f-80AD-7E09334BB852}
  • FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042
  • SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}
  • SystemMailbox{1f05a927-b536-4dbb-9e08-dff2ecc40e1a}

Then you have to enabled it from EMS


that’s it! Open-mouthed smile it’s a wrap Open-mouthed smile

I’m using the DiscoverySearchMailbox for Multi-Mailbox Search Smile , references : http://technet.microsoft.com/en-us/library/gg588318.aspx
