MS Exchange 2010 - Offline Address Book Won't Update
Posted on 2013-05-21
I have a single MS Exchange 2010 server. This server was upgraded from an MS Exchange 2003 server about a year ago (not sure if that is relevant).
Well within the last month or so, the Offline Address Book quit updating.
All of my clients are Cached clients (which I want to keep) and the offline address book will not update.
The GAL is fine, because if you turn off caching or out OWA the address book is current.
I have found that if I blow away the OAB files manually on a client they pull down again and the address book is correct, however, I can't really go to 100 clients to do this, I also don't think it is then updating again after that.
Can anyone help as to why this is happening?
