Note from the Editor
Greetings PHILIP,
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 Exchan! ge 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.

And once you’ve deployed Exchange Server 2007 Edge Transport servers to control spam and other unwanted e-mail messages, you’ll want to implement logging and tracing and configure Edge Transport agents to perform the tasks you need. Check out the November issue of TechNet Magazine to see how to analyze Edge Transport agents in action by using the standard agent logging and tracing features of Exchange Server 2007.

The 2007 Microsoft Office release includes hundreds of security and privacy settings. Download the 2007 Microsoft Office Security Guide for best practices and automated tools to help strengthen the security of computers that run either Windows Vista or Windows XP SP2 and applications in the 2007 Microsoft Office suite.

Windows Vista is the first PC operating system designed with infrastructure management as a core focus, and Microsoft has launched a new resource for IT pros to make the adoption process smoother and better guided. The Springboard Series for Windows Vista is now available on a new TechNet destination. This offers monthly articles based on community feedback and helps answer key questions around how and why to get going with Windows Vista adoption. The Springboard Series itself is designed to more simply guide you through the entire adoption process, from early exploration of new management capabilities through piloting and finally rolling out through your organization.

Thanks for reading,
