I hope somebody will be able to offer a nugget of information here, as I'm currently struggling with an offline address book related issue. I have a customer connecting via VPN to an Exchange 2003 environment from home. He recently reported that his Outlook Global Address List wasn't up to date, and upon investigating remotely I realised that he was running Outlook in Cached Exchange Mode. If this is disabled and Outlook is restarted the GAL will update. However, if I then enable Cached Exchange Mode again and restart the GAL reverts to the old Offline copy, which is once again out of date.
I've tried manually downloading it via the 'Send/Receive' menu, but this has made no difference. I've rebuilt the offline address book through ESM and manually downloaded it at client end, and again it's made no difference.
I'm at a bit of a loss at the moment I'm afraid! The address book is set to update daily at around 5am, but this doesn't seem to take effect for this user. If anyone has any ideas or possible troubleshooting methods I'd be very grateful to hear them!
Thanks very much.
