We are in 2007-2013 co-existence. There don't seem to be any organizational mailboxes in the 2013 environment. Get-mailbox -Arbitration returns nothing on either of the two servers in the DAG. I found this via troubleshooting why the OAB isn't updating for migrated clients.
Any ideas on how to resolve this or why they don't seem to be there? I also tried migrating system mailboxes from the 2007 environment but the five of them failed saying they already existed in the database, which was odd.
Thank you,
Kurt
