Is a Windows Server 2012 Standard and Datacenter CAL required for users accessing a Datacenter edition Windows Server?

I have always hated MS's licensing model, which is why i count on CDW to tell me what i need. Recently, a colleague of mine said that you need two CAL's for each user if you run Server 2012 Datacenter - The Datacenter CAL on top of a Standard CAL. I have never heard of this, and can't find any MS (or other) documentation that says this, and i would hope CDW is not wrong, but it wouldn't be the first time they were

No such thing as a "standard" or "datacenter" CAL when it comes to Windows CALs. A Windows CAL covers either Standard or Datacenter editions.

As always, licensing advice on EE is *NOT LEGALLY BINDING.*  Licensing questions should be directed at Microsoft through their pre-sales line. Like a stranger offering a kid candy from the back of his/her van, you can't trust anybody's intentions here.

I meant Exchange User CAL, and Std/Enterprise, not Std/Datacenter. Been going through a lot of licensing this week. So, let me correct my question;

Do you need two CAL's for each user if you run Exchange Server 2012 Enterprise? The Exchange Ent. CAL on top of a Standard CAL?

Well, this isn't a confusing licensing issue. It is a confusing *naming* issue.

If you use any of the enterprise features (archiving, Unified Messaging, etc) then you need a standard *and* an enterprise CAL. Yes, you need two. Those features are available on both Exchange Standard and Exchange Enterprise editions.

If you are *not* using the Enterprise CAL features then you do not need to add Enterprise CALs, *even* if you are running the Exchange Enterprise edition.

The server edition and the CAL editions share the same name, but mean two completely different things.

So like I said, the licensing is actually simple. But the name makes it confusing.
