Exchange 2010 Licensing Considerations

Exchange 2010 is now in the price files so you can all go out and buy it 🙂 There is a lot of information about the technical differences, but not so much about the licensing changes…so let me change that 😉

Replication Licensing

The current “Local Continuous Replication” is being replaced by “Mailbox Resiliency” in 2010; Mailbox resiliency requires 2 active instances of Exchange 2010…and thus 2 licences.

As a one-time exception, customers with Exchange 2007 and Software Assurance (SA) on Select, Enterprise Agreement, Open, Open Value, Campus & School get:

“One complimentary Exchange Server 2010 Standard license for each datacenter where the customer has at least one server licensed for Exchange Server 2007 Standard with active Software Assurance as of November 1, 2009.”

The additional licences that you receive under this offer all included SA that expires at the same time as your originally purchased licence.

As an additional offer, if your Exchange SA expires between November 1st 2009 – November 1st 2010 you can renew just the SA for the original licence, and that will also renew the SA for the 2nd additional licence 🙂 However, after that the licences will need to be renewed separately.
