I have 2 Exchange 2013 mailbox servers as members of a DAG, with different Active Databases on both server. One of the servers gets the Offline addressbook however the other one the addressbook files are over a month old. I have restarted the Exchange Mailbox Assistant on the problem server and tried running the Update-OfflineAddressBook powershell command. The problem server is not updating at all. I have even gone to the point of renaming the E:\Exchange\ClientAccess\OAB\{OfflineAddressBookGuid} folder. The server does not generate a new one and the files in here at over a month old.

Any ideas on how I can troubleshoot this one?

I didn't think the CAS servers were involved in Exchange 2013. I thought it was just the Exchange 2013 Mailbox Servers. Do you see anything wrong with the output below.

Hi,

Please use following command to list the arbitration mailboxes with persisted capability of OABGen and database on which this mailbox is hosted:

Get-Mailbox -Arbitration | where {$_.PersistedCapabilities -like "*oab*"} | ft name,database

Then identify the mailbox server where the database hosting organization mailbox is mounted

Get-MailboxDatabaseCopyStatus DB

The OAB is generated by arbitration mailboxes with persisted capability of OABGen, so which mailbox server where the database hosting organization mailbox is mounted then which mailbox server will generate OAB.

To know more about OAB generation in DAG, I recommend this blog.

http://blogs.technet.com/b/exchange/archive/2012/10/26/oab-in-exchange-server-2013.aspx

Best Regards.

Thanks for the response.

I did actually get this resolved in the end by moving the Arbitration mailbox back to the original database it was created within. I had come across the article you mentioned above while researching the issue that pointed me in the right direction. I have a much better understanding now of how Exchange 2013 deals with OAB generation.
