Hi,I am going to buy Ms Exchange server but confuse with the price, licensing and how many users can use.For example, if i buy Exchange Server 2007 Enterprise Edition, i will get 50 storage groups, is this the same as 50 users? and if i need more than 50 users, i could just buy The Exchange Server Enterprise CAL? depending how many more users i need. Is that the way of buying the product?I am not familiar with Ms Exchange server, but i need info about how many domain name can Ms Exchange Server support?For example, if i buy Exchange Server 2007 Enterprise Edition, do i get 50 domain name? Thank you, really appreciate for the help.

Storage Groups and user license are not logically related. ~ For a Exchange server you need to have Exchange 2007 Enterprise or Standard edition license. ~ For users you need to have Standard, Enterprise or both type of CAL depending on usage for each users/devices. ~ About domain names, I didn't see any limitation on number of domains in Exchange. Further detail about Exchange server license and CAL you can find in below articles...
