At long last! Service Pack 2 for Microsoft Entourage 2004 is now available!
I was the Program Manager heading up this effort from August 2004, through May 2005, and I am damn proud of the Entourage team for this accomplishment.
This is release is one that will make any Exchange using Entourage customer happy. Amazing and awesome improvements have been made to Public Folders, Calendar Syncing, Delegation, GAL, and Permissions. It even supports multiple Exchange calendars and address books! I’ve been using this and it has been great! Some of the things I used to do in Entourage are now 4x faster - fantastic! It’s all part of the MacBU’s continued commitment to delivering value to its customers, and to enable Mac users exist seamlessly within a PC world.
In the long standing tradition of the MacBU, there is even a Mac first, and Mac only feature in this release. I’m going to leave it to you to figure it out though 
To be able to use this version of Entourage to its fullest potential, you will need to talk to your Exchange administrator about applying these hotfixes:
KB892986: The value for the PR_ACCESS property that is returned from a WebDAV PROPFIND method is always MAPI_ACCESS_READ (read-only) in Exchange 2000
KB888619: The value for the PR_ACCESS property that is returned from the DAV PROPFIND method is always read-only in Exchange Server 2003
As you can see - one fix is for Exchange Server 2003, and the other is for Exchange Server 2000. I want to emphasize that these two fixes are not Mac specific - but are recommended fixes for Exchange.
If you have any questions about this release, I highly recommend you check out the following resources:
1. The Microsoft Entourage newsgroup
2. The Microsoft Entourage mailing list
3. The Microsoft Entourage MVP website
4. Your Exchange administrator - after all, she will need to apply the above fixes.
You can of course leave a comment, but do I remember that I now work at MSN Search Toolbar.
Congrats again to the Entourage team, and the rest of the MacBU for this fantastic release!
