1. Outbound Faxing
2. Certificate Generator for SANs that will place certificate names in the proper order depending on needs
3. Better/more migration tools that will assist in making it easier for us to migrate to Exchange 2007.
4. Mailbox Items and Size in GUI.
5. Better Message Tracking System
6. Better support for configuring Autodiscover service in the EMC. Both for InternalURL and ExternalURL for ALL services including the ability to enable SSL for these services and their authentication settings.
7. Owa premium for Firefox
8. Don't release an incomplete product. Almost everybody I talk to agrees RTM was released too early. Functions that were used in Exchange 2003 should not have been postponed to 2007 SP1. If needed, push back the RTM date.
9. AND PLEASE.... allow us to set calendar permissions via a GPO or via some other method. For instance, in our organization, we have Default - Reviewer so everybody can view each other's calendar. And when I said better migration tools, that means the functionality to be able to share this cross-forest as well, and not just free/busy.
10. Better functionality for sharing free/busy and calendar data with newer versions of Exchange. I'm assuming this will be better in Exchange 14 due to it most likely using Availability service.
