Back in November 2012, Microsoft confirmed that Skype will replace Messenger in all countries worldwide in the first quarter of 2013 (with the exception of mainland China). In order to focus the development efforts and create seamless experiences, Microsoft decided to do end Messenger service and go with Skype. Last month, Microsoft sent out notifications to Messenger users in China that the service will be closing down the service on October 31st. Users are recommended to migrate to Skype service and Microsoft is also offering 60 minutes of free calls to mobile and fixed lines globally to all these new users.
As Messenger service will be completely closed by October this year, Microsoft has decided to give the @Messenger Twitter handle to Facebook. Facebook now has a messaging service called Messenger on its own, I guess they will use @Messenger Twitter account for its purpose.
