Just while I'm in Redmond to discuss the next version of Office, Office 2010, the second service pack for Office 2007 came available for download.

So if you think you found some bugs in Office 2007 SP1 or earlier, install Service Pack 2 to check if your issues have gone away.

The 2007 Microsoft Office Suite Service Pack 2 (SP2)

From my own experience I know that at least the performance improved a lot for Outlook. And that alone for me is a reason to install the Service Pack without delay.

Is this Service Pack an improvement for your installation? Let me know!
