Microsoft to drop Facebook, Google Chat integration in Outlook.com
Within "the next couple of weeks," Microsoft will discontinue support for Facebook Chat and Google Chat in Outlook.com.
Microsoft notified Outlook.com customers of the pending change via an e-mail message from the Outlook.com team sent on February 24
(Thanks @lindhartsen)Microsoft attributed the decision to drop Google Chat integration to Google's decision to discontinue the chat protocol used by the Google Talk platform.
