Exchange 2013 licensing

Hi Experts,

I plan to buy and install Exchange Server 2013 within DAG.
Lets say I will have

2 CAS
2 HUB
2 MBX

The Windows OS will be 2012 R2 STD.
Is it correct that I don´t need Windows Enterprise 2012 R2 Edition for it ?

The Exchange version will be 2013 STD.

How many licenses do I need for Exchange 2013 ?

Is it correct that I don´t need Windows Enterprise 2012 R2 Edition for it ?

there is no windows 2012 enterprise; only standard and datacenter which both support exchange 2013

In this case normally you don't Need the Enterprise license for Windows. The two Exchange Server will replicate on their own, not Windows Cluster is required. And also the other roles not require Enterprise Servers.

look at the link i posted earlier regarding system requirements
mailbox, client access, edge transport roles can use either standard or datacenter
there is NO enterprise edition of windows 2012

Ok I have read your link and about WINDOWS I know it now.
But what about Exchange STD licenses ?
Do I need an Exchange License for all CAS , HUB and MBX Server ?

I have seen, the exchange roles have changed, from 5 to 3.
What about the HUB TRANPORT role ? Where is it now integrated ?

Does a CAS Server in Exchange 2013 need a Exchange Server 2013 STD license ?
