Hi, You can install the Exchange 2007 Enterprise on Server 2008 Standard, but bear in mind that you won't have any failover solution in terms of clustering.

hi, im also planing to purchase windows 2008 std with exchange 2010 std editions but rite now im planing to purchase 10 CAL for each product 10 for windows server and 10 for exchange but if i want to purchase more licenses after previous purchase then you know windows 2008 have no clint licenses console so what should i do when we purchase more licenses in future regards

Hi, you can install E2007 Std\Ent on W2008 Std\Ent when E2007 is installed on W2008 std, Cluster features (WFC and NLB) won't be available. Since Cluster is a Windows enterprise feature. if its a small company would be running one\two servers without HA configuration then you can go for W2008 Std. CALs require to avail the Exchange server features (depends on your requirement) also refer: http://blogs.technet.com/b/scottschnoll/archive/2006/12/31/exchange-2007-platforms-and-product-keys.aspx Regards, Hari | MCSE+ Messaging
