Starting April 8th, we will begin upgrading customers from Messenger to Skype. The process will take a few weeks to complete. April 8th is the first day you may be required to upgrade. This is a bit later than the March 15th date we previously mentioned to some of you as we wanted to give you more time to make the transition.
To keep chatting with your Messenger contacts, simply upgrade to the latest version of Skype using the instructions below and sign in using a Microsoft account (this is the same ID you use to sign into Messenger). Once signed in, your contacts will already be there. You’ll be able to instant message and make video calls with them just like before, and start discovering new ways of staying in touch, including Skype on your mobile or tablet.
