Good news, social butterflies! Nearly a year after Microsoft first added Skype functionality to Outlook.com on a preview basis, the communication tool is officially rolling out to inboxes throughout the world—complete with new HD video calling capabilities.

That'll make your face-to-face chat's clearer than before, but the Outlook.com functionality also includes the voice calls and instant messaging Skype is so famous for. You'll need Skype's browser plugin to get the ball rolling. A Safari plugin is now available so Mac users can get in on the real-time communications action.

The rollout also squashes a particularly bothersome bug. If you were running both Skype on the desktop and Skype in Outlook.com, incoming calls could continue to ring even after you picked up. No more.

Once you've downloaded the plugin, you'll need to link your Skype account to your Microsoft account to take advantage of the in-Outlook calling.
