Live meeting button integration behavior during MOC to Lync upgrade

The first screen shot shows the Outlook with the Live Meeting Addin, pressing the “Schedule a Live Meeting” button creates a Live Meeting appointment as one would expect (Red box)

We can also see the meeting link has the meet:// verb meaning that meeting is Live Meeting based (OCS AV server will host it

After running a default install of Lync (the Lync installation program may prompt to close Outlook) We can see the Live Meeting button has been replaced in Outlook. The “Online Meeting” (red box) and the meeting invite link is now https://...., indicating this is now a Lync based meeting.  Should this user need to join a meeting that was created in OCS, the Live meeting client will be leveraged. We can see below that the Live Meeting client is still installed.

However to use Live meeting add-in along with Lync Online meetings (to ease the co-existence) phase, use the below registry entry (with value of 0) on the client computer to restore functionality :


HKLM\Software\Microsoft\Communicator\W13AddinSwitch

Value = 0 : w13 has full UI.

Value = 1 : no w13 OCS functions. W13 Only shows Live meeting service functions.

Value = 2 : no w13 UI at all.

UI = user Interface

W13= OCS 2007 R2
