Back in January, Microsoft launched Outlook for iOS and Android, designed to help users of the two most popular mobile platforms manage their email and calendars. The new apps, which came about after the acquisition of Accompli, is part of the company’s push to provide productivity tools across platforms—even those it doesn’t own. In the case of Outlook, that seems to be paying off.
Microsoft announced Wednesday that 30 million people use Outlook for iOS and Android every month. That’s some serious traction for a heavy-duty productivity app, and it also consistently holds a position among the top 20 most downloaded productivity apps in both the Google Play Store and iOS App Store. (In the grand scheme of things, Outlook’s position isn’t nearly as strong as Facebook’s, which reported in July that it had one of the most popular apps with 1.31 billion monthly active users on mobile.)
