As usual, the Microsoft Office 2007 web site is not very clear on the subject. I haven't found anything that definitely says Outlook will or will not be sold separately, but I did find a site with individual pricing for Outlook: http://office.microsoft.com/en-us/products/FX101754511033.aspx?pid=CL100796341033

Rowan, Are you using Sharepoint 2007 at all? We're looking to take the leap into an Enterprise Content Management system next year, and we were going to evaluation Sharepoint 2007 as one of them. Any info would be welcome.
