Rebranding started in 2014. In March 2014, Nokia Mail and Nokia Chat were closed, offering migration services to Microsoft's Outlook.com and Skype until April 2015.[68] All Nokia accounts were closed on 25 April 2015.[69][70][71] Most of Nokia's social media sites were rebranded as Microsoft Lumia[72][73][74][75] rather than Microsoft Mobile, to emphasize their focus on Windows Phone as opposed to other Nokia mobile phones.
