This service pack includes major performance enhancements for Office applications, most notably Microsoft Office Outlook, as well as Microsoft Office SharePoint Server. One big benefit is SP2’s boost to interoperability — with this release, Office supports additional built-in file formats such as PDF and ODF.

This release builds on customer feedback and offers enhanced stability for Outlook, calendaring reliability, and many more improvements to applications that run on both PCs and servers. Microsoft has also been working hard to build interoperability into its products across the board, and so Office now also includes additional file-format support, which makes it much easier for customers to work with different file formats in the same application.

Users should notice the improved performance and stability of Outlook, better charting functionality in Excel, and more control over the appearance of SmartArt graphics.

On the server side, IT professionals will notice several enhancements to the security and performance of SharePoint Server 2007, including support for read-only content databases, improvements to forms-based authentication, and an STSADM command-line utility that enables administrators to scan sites that use the variations feature for errors. SharePoint Server will also feature better support for newer versions of the Firefox browser.
