Exchange Active Passive Cluster licensing CALs

Im getting ready to purchase a new exchange server (2007 Enterprise Edition). I am considering building and active passive cluster. I currently have 200 users on my Exchange box. Im sure I have to get 2 Licenses each for both Win2k3 Server and Exchange 2007 EE; but would I have to get 400 CALs even though this will be and Active/Passive cluster??

thanks

Tom

Exchange is only licensed per seat, not per server.
Therefore if you have 200 users then you will need 200 Exchange CALs and 200 Windows CALs - although you probably have those.
You will need an application license for both servers for Windows and Exchange.

I understand that but my question is do I need an additional 200 CALs of  server and 200 CALs of exchange for the passive cluster (totalling 800 CALS)?

Where did you get that idea from?
Do you not understand the concept of per seat licensing?

I got that idea from my MS software sales rep. He said I need separate CALs for each of my cluster nodes in an Exchange 2007 Active Passive cluster. If i understood the licensing aspect of clustering I would not be posting here. Sorry..

Was that someone at Microsoft stating that, or a reseller?
If it was a reseller then someone has been trying to get you to purchase more than you need.

Exchange always has been licensed per seat. It doesn't matter how many servers you have, the number of CALs remains the same.

However, everything I have written above is of no value to you.
The only people who can confirm licensing details are Microsoft. No one else, resellers or anyone is authorised to confirm or deny how the product should be licensed. When you get a response from Microsoft ensure that it is in writing.
