On Friday, December 8, 2006, Exchange Server 2007 was released to manufacturing!  w00t!  See http://msexchangeteam.com/archive/2006/12/07/431782.aspx for a signoff note from our General Manager, Terry Myerson.  The final build number is 8.0.685.25 (note that the build will show in some places as 8.0.685.24; this is known issue and nothing to be worried about).

After 2 ½ years of upgrading Microsoft's internal Exchange servers, we now have 125,319 mailboxes on Exchange 2007 at Microsoft, with 30,372 enabled for Unified Messaging. We also have over 200 Technology Adoption Partners and Rapid Deployment Partners have over 55,000 mailboxes in production operating within their enterprise SLA’s. You can read more about how we did Exchange 2007 internally at http://msexchangeteam.com/archive/2006/12/07/431793.aspx.
