Today the availability of Service Pack 2 (SP2) for the 2007 Microsoft Office system was announced.
The 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.
In addition, Microsoft will release SP2 via Microsoft Update’s automatic update mechanism no sooner than three months from now, and with at least 30 days notice, which aligns with their prior established policy.
