Contact missing from Outlook after adding new user in Active Directory

If I add a new user account/email to our Active Directory, it can sometimes take a day for that new person to appear on everyone's built in Contact list under Outlook.  Why is this?  Is this an Outlook 2007 problem or an Active Directory/Exchange problem?   The new user won't appear after a log off/log on either.   I'll forget about this issue and then the user name will magically appear later without any intervention from me.  How can I force new users to appear under the Global Address List composing an new email and hitting the "To..." button?

The Recipient Update Service is an Exchange service which scans Active Directory looking for flags that tell it to create a new mailbox.  This service is also responsible for updating the address lists.  It pulls this information from the global catalog in Active Directory.

To maximize the efficiency of this process, make sure a global catalog server is in the same site as the Exchange server running RUS (it will be your SBS server).

If you want to force the issue, then after you create a user, go into the Exchange System Manager, expand Recipients, Recipient Update Service and then right-click on each of the objects there and select "Update Now".

Hope that helps!
