We want to install Exchange 2003 (migrating from Exchange 2000, Windows 2000
domain).
The product Exchange 2003 is no longer available from Microsoft. So we have
purchased Exchange 2007 CDs, Keys, CALs.

May we install Exchange 2003 instead and how to proceed with Microsoft in
this kind of situation?

Regards,

Licensing questions are best answered by your software vendor or Microsoft
rep.

Having said that, don't think this is an issue. Downgrade rights allows you
to license a current SKU and install a previous version that's no longer
being sold, till you're ready to upgrade. As long as you don't run both
versions simultaneously (i.e. get license for one product and use both), you
should be OK.

There's a Downgrade Rights chart at
http://download.microsoft.com/download/d/2/3/d23b9533-169d-4996-b198-7b9d3fe15611/downgrade_chart.doc -
(doesn't specifically talk about Exchange iirc).
