If I took the Outlook 2007 client out of cached mode, they would see the latest address book.
The way we fixed this was by going into Exchange Management Console (EMC) , Organization Configuration , Mailboxand then clicking on the Offline Address Book tab.
Double click on the Default Offline Address Book then click on the Distribution tab and untick “enable web based distribution” .
When this message comes up, click Back, select Manually configure server settings then click Next.
You'll need to enter your account information and server names then click More Settings and configure your SSL or TLS settings on the Advanced tab.

We had a problem where any new user mailboxes that were added to the Exchange server were not appearing in the address books of Outlook 2007 clients running in cached mode.
The address book was up to date in OWA, but our cached Outlook clients wouldn’t update even after forcing a download of the OAB.
The message that comes up when Outlook can't set up an encrypted connection automatically caught a couple of users off guard this week.
After calling their mail provider to verify the account supports encryption, they asked me what was wrong with Outlook.
