Here’s the deal. I’ve got the new Lync client. Which is great!! But we’re still running OCS2007 internaly.

So I can only use Lync to connect to Office365. That’s a bit of a bummer.

But, it can be done! You can connect Lync to OCS and ignore the error-message.

Just add the following setting to your registry:

Key: HKEY_CURRENT_USER\Software\Policies\Microsoft\Communicator
Name:  DisableServerCheck
Type: DWORD
Value: 1 (00000001)

Please note: this is a new registry setting in the Policies\Microsoft hyve. So add the Communicator key and then the DWORD.

Of-course, some of the Lync specific functions won’t function. But chat, audio, video and application sharing works perfect!
