In one of my earlier post I commented on how to connect to OCS (R2) using the Lync client. Now with the release of the new Lync 2013 client, this “work-around” doesn’t work anymore. But there is a new one. To use the Lync 2013 client with an older server-version like OCS 2007, just add the following registry key (create it, because it does not exist):
This is a DWORD key and it should be set to “1”.
Now you can logon to OCS (R2), but work with this beautifull new client 🙂
