Microsoft SharePoint is famous for its ease of creating -- and abandoning -- local workgroup portals. As readers of our latest Enterprise Portals Report know, this has not fundamentally changed in MOSS 2007. Yesterday, Shawn Shell (former Dell consultant turned indie SharePoint guru) reminded me that administrators can set a SharePoint site to generate daily e-mails to a site owner when it goes unused after a specified period, say 30 days. Optionally, you can configure a SharePoint site to delete itself after X days thereafter. Microsoft's genius here lies in recognizing that project teams often really do want disposable collaboration spaces. But if you're a records and information manager who cares about liability and retention, you're probably getting a little queasy right now. Those who require firm, enterprise-level administration and control may need to look elsewhere for their portal solution.
