Dear Expert,

I have used OCS 2007 R2, I know OCS can federate MSN, AOL and Yahoo. I would like to know.

1. What's the hardware and Software that I should prepare. For example, OCS Gateway

2. Need more any license?

3. How do I deployment and plug with existing Server.

4. Any suggestion.

Thank you for your helping.

First, you have to deploy a OCS 2007 R2 edge Server for public Federation.

I think you can follow this link, for the rest of the needed Configuration.

Hi,

The OCS 2007 R2 edge Server must be required for OCS/Lync federation.
