Solution

Note: If you don't have any Outlook 2003 clients left in the organisation, this is a moot point. Simply disable distribution of the offline address book via public folder. (Newer Outlook clients use web based distribution.)

1. Before we do anything make sure that the offline address book has been specified, is shown on the correct server, and is set as default.

2. From the Exchange Management Console > Toolbox > Public Folder Management > system Public Folders > OFFLINE ADDRESS BOOK > Then in the center window, right click each one > Properties > Replication > The server that hosts the public folder should be in here > (In my case it was not.) > Add it in.

3. Now you can force the OAB to update with the following command;

Get-OfflineAddressBook | Update-OfflineAddressBook

4. Now recheck the event logs, and you should no longer get Events 9335 and 9331.
