Hi All,
Recently all of my Outlook 2013 clients have started having issues when communicating with the Offline Address Book. When I force an address book download, it appears to work fine however when I select an Address List from the GAL (such as All Users or All Contacts), Outlook hangs for 1 minute then returns the error:
The operation could not be completed because an offline address book is not available. Download a copy of the offline address book.
My OWA works perfectly fine and the Address lists work fine in OWA, its only on the client that this fails. To the best of my knowledge the OAB is generating successfully and clients are downloading it.
I am running Exchange Server 2013 with 2 CAS servers and 3 MBX servers (in DAG) and all running CU2.
I haven't found any results online of people with similar issues so I don't even know how to go about diagnosing the issue. Any help greatly appreciated.
Thanks Christoph
