Exchange 2007 SP1 running on Windows 2003 server - All clients running Outlook 2007
New to Experts Exchange so please bare with me. We recently decommissioned our Exchange 2003 server from a co-existing setup between 2003 and 2007 while following the steps outlined in Microsoft's KB article. Since we got rid of the 2003 Exchange, we have been unable to get new users to show up in our GAL. Created a custom Address list and all users populate in this address list. OAB was an issue at first but has since been resolved and the OAB is pushing to clients now but GAL remains the same. Exchange Logs are clean and not showing any errors pertaining to GAL.
So to summarize, both Cached Mode and Online mode cannot see new users in GAL. And of course, cannot setup the "missing" users in Outlook 2007 as I believe Outlook looks at the GAL to resolve, receive error "the name cannot be matched to a name in the address list".
Can someone point me in the right direction with this? I've been trying to solve this one for weeks.
Thank you very much for your help in advance.
