Microsoft has sent an email to Messenger informing them that the service will be closing on 15 March 2013.
Skype was acquired by Microsoft in 2011, and recent changes to Skype have allowed users to sign-in using their Microsoft Account, meaning migration is pretty straightforward.
The email says the change will affect all users except those in China, where Messenger will continue to be available.
Essentially there's little to the transition process: all you have to do is head over to Skype, download the software and sign-in with your Microsoft Account and you'll find your Messenger contacts available there.
The Skype software, on desktop or mobile devices, currently lets you sign-in with either your Skype ID or Microsoft Account.
If you're concerned about the move, then don't be. We've found our Messenger contacts are all present and correct, and Skype's wide range of cross-platform support and services brings plenty of advantages.
So mark your calendar for 15 March, or better still, just head over and download the Skype software and make the move today.
