When we released Beta 1, we promised the release would be available to MSDN and TechNet subscribers early this year. Well, that time has come. Beta 1 is now being distributed via CD shipping to TechNet subscribers; MSDN subscribers will be able to download the CTP in March.
This CTP includes both the full 64-bit version, and the 32-bit version for feature evaluation, training, and demonstrations.
The latter is interesting since Exchange 12 is supposed to be 64-bit only. More by following the link including that Beta 2 is due in mid 2006 as a public CTP. The ship date is still projected to be “end of 2006 or early 2007.” One new feature of Exchange 12 that’s drawing buzz is continuous replication between Exchange servers.
