MICROSOFT has announced that it is putting its Windows Live Messenger service to rest.
All Messenger users will be switched over to free online conference and calling service Skype on March 15.
In a mass email to users of the chat service, the company said "we are retiring the existing Messenger service globally".
The move follows Microsoft's acquisition of Skype in October last year for $ A8 billion.
Skype was created by a team of Estonian software developers and was released in 2003. It went on to gain more than 600 million users before it was bought by Microsoft.
