OCS 2007 R2 Documentation

You also noticed that when you search for OCS 2007 R2 documentation, you get a lot of OCS 2007 documents? Drove me crazy, whenever I followed a link on a OCS 2007 R2 site, I got to OCS 2007 knowledge base.

So I decided to make a collection of true OCS 2007 R2 document libraries, to facilitate my OCS 2007 R2 - Cisco Call Manager integration project:
1. Microsoft Office Communications Server 2007 R2
The mother load, from the Microsoft download center. I just don't understand why this doesn't show up when you Google it.
2. Microsoft Office Communications Server 2007 R2 Documentation
A CHM file with technical documentation to help you understand, plan, deploy, and operate Microsoft Office Communications Server 2007 R2 servers.
Remember that you might have to "Unblock" the content.
If you need help on that, here is the Microsoft support page: You cannot open HTML Help (.chm) files from Internet Explorer
3. Microsoft Office Communications Server 2007 R2 online documentation
If you don't want to mess about with the .chm file, you can find the same documentation online, on the Technet pages.

Hope this can help you on your OCS search.
