Re-creating arbitration mailboxes in Exchange Server 2013

Sometimes due to reasons such as mailbox corruption, general odditities and so forth - you might be in the situation where you are missing a system mailbox and need to re-create all of them.

By default the following lists all of the default arbitration mailboxes created during the installation of Exchange 2013:

SystemMailbox{1f05a927-eac1-46e7-9a47-611e1a81bb50}
SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}
SystemMailbox{bb558c35-97f1-4cb9-8ff7-d53741dc928c}
Migration.8f3e7716-2011-43e4-96b1-aba62d229136

 We should re-run a portion of the Exchange 2013 setup as follows:

setup.exe /prepareAd

And finally ensure all of the newly created arbitration inboxes have been enabled - so for each mailbox we run:

Enable-Mailbox –Arbitration "SystemMailbox<Guid-Value>"
