How to Configure LYNC 2013 and Exchange 2010 OWA Integration
Applies to Exchange 2010 and Lync 2013 Server.
There is a doc about Lync 2013 and exchange 2013 Integration (http://technet.microsoft.com/en-us/library/jj688055.aspx). But there is an ambiguity about Lync 2013 and Exchange 2010 Integration in the doc. In addition I tested the doc and did not work.
Also there is no other clear docs about it.
Here is my working solution. Actually same steps for Lync 2010 and Exchange 2010 OWA Integration.
Applied the steps explained here:
But I had installed Unified Communications Managed API 4.0 Runtime and .Net Frame work 4.5 on Exchange 2010 server before. (Although I do not believe these are necessary)
And then applied each step in http://www.expta.com. And it worked.
