On November 30, you will be able to download Exchange Server 2007 with Service Pack 1. The list of new features in SP1 is long, including new deployment options, new features and improvements for each server role, improved integration with other applications, and even a new, third type of continuous replication. There are also general updates to almost all of the high availability topics for SP1, as well as significant updates in other content areas, such as those related to the Mailbox, Client Access, Hub Transport and Edge Transport, and the Unified Messaging server roles. You can find documentation on the new features by browsing or searching the Exchange Server TechCenter Library. If you’re in evaluation mode, you can now download the Exchange Server 2007 with Service Pack 1 trial software and see how secure, anywhere access can enhance operational efficiency.
