I note with interest that today Microsoft released Update Rollup 8 for Exchange Server 2007 Service Pack 1. Basically this is a collection of fixes since they released Exchange 2007 Service Pack 1 and can be applied to a server without the need to apply the previous rollup packages. The question comes to mind though, is when is a service pack now different to a rollup?
You can get the Update Rollup 8 for Exchange Server 2007 Service Pack 1 packages from here http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=e1f5c8b2-c4f2-4eba-849b-e464d4f2869c#tm
No news yet on if this helps anything SBS 2008 related, I ll admit that I plan to apply this to my servers over the weekend.
