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?

The files should show up in two places.  The one under ExchangeOAB is what's generated and will be current only on the generating server.  In fact, if a server has never been the generating server the folder will not exist at all.  If you have properly configured web distribution, the current files should show up on each CAS under ClientA

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.

You're right, I forgot that Exchange 2013 looks up the OAB in a system mailbox.  The VirtualDirectories property shows that you have two dual-role servers that are both configured to serve the OAB.
