Office Communications Server 2007 R2 launches via a virtual launch on Feb. 3, from 9:30am – 10:30 am PST. This launch event will have sessions to provide details on the new features and capabilities of the R2 wave as well as demos so you can see R2 in action.
You can get details on what���s new in Office Communications Server 2007 R2 here.
You can register for the event here.
Feb. 3 is also the date the platform SDKs will be posted to the download center. I’ll post links on my blog when that happens. Combined with the eval copies of Office Communications Server 2007 R2 and Office Communicator 2007 R2, you can quickly set up a development environment for “kicking the tires” of the new R2 platform SDKs.
