I have outlook 2010 clients SP1 & all patches in cached mode connecting to an Exchange 2007 server. My issue is that the clients are not running with the latest version of the offline address book from the server. I have verified that the OAB is being
updated properly on the server. Doing a manual update using send/receive of the OAB from the client does not work. If I delete the OAB directory on the client the address book is updated to the current version when the client is first opened. Turning off cached
mode does not fix the issue, and at any rate my environment must run in cached mode. I have temporarily put in a logon script to delete the OAB on the clients which is working, but I would rather have a proper fix. If anyone has seen this let me know.
Thanks;
Don
