Sorry, this comment has nothing to do with the topic above, but maybe you could address it in a formal post.
As an admin for a small-mid-sized-and-growing business on a budget, one thing I really liked with Exchange 2003 is that a license to Outlook 2003 came with every CAL.
This link concerns me.

It seems that purchasing CALs for Exchange 2007 will get you nothing in the way of software to actually *use* the CALs. Outlook 2007 will have to be purchased for each user, unless my company is enrolled in Software Assurance (which is not cost effective for us).
I find Microsoft licensing very confusing above the simple outright purchase level, so I'd appreciate any light you could shine here, including comments on how licensing upgrades from Exchange 2003 CALs are affected.
Thanks for any info.
