If you are using Entourage 2004 to connect to Exchange 2000 and notice that some mail folders show up in other Exchange clients (OWA or Outlook), but aren't showing up in Entourage, then your Exchange server may need this recently released Exchange 2000 hotfix. After applying the hotfix, you should follow these steps to get the folders back in Entourage (this text is copied from the end of section 5.2 of the Entourage 2004 readme):
If Exchange account mail folders are visible in Outlook but not in Entourage, make sure you have installed the latest update to Exchange. To access Exchange account folders within Entourage, use Outlook or Outlook Web Access (OWA) to rename the folder and then rename it again to its original name. The folder will then be visible within Entourage.
