The webcam feature is only usable on both sides. The feature “Show my Webcam” is no longer available. If you now click the webcam icon next to your display picture, a Video Call will start directly. If the recent Messenger 2009 update (Build 8117) has not been installed yet, pending single-side webcam invitations will be rejected automatically server-side.
But I’m wondering: I haven’t installed nor received any update for Messenger yet, and still… will features of the new Messenger come to my PC silently this way?
Update: I’ve tested the Video Call feature and am thrilled about its picture quality. Though, one problem remains: you only can “cam” with one person at once. I assume this is something we have to get used to.
