Microsoft might lose a whole city of customers in Russia. According to Bloomberg, Moscow will begin replacing Redmond's products with homegrown software as a result of Vladimir Putin's urging to stop depending on foreign tech. Artem Yermolaev, the city's head of information technology, told reporters that Moscow will begin by dropping Microsoft's Exchange Service and by replacing Outlook on 6,000 computers with state-run carrier Rostelecom PJSC's email system. Authorities are looking to deploy the email software to as many as 600,000 computers in the future. They might even replace Windows and the Office suite entirely, though there seems to be no solid plan for that at the moment.
