Microsoft's popular Outlook email app has surpassed 100 million installs on Google's Android app store.
Reaching 100 million installs on the Play Store may be a significant milestone for Microsoft's email app for iOS and Android, but it's still a long way behind the Google Gmail app and the Samsung Email app, which have five billion and one billion installs, respectively.
Nonetheless it suggests progress on Microsoft's mid-2019 update that the Outlook apps on iOS and Android had surpassed more than 100 million users, which is a different metric to installs from the Play Store.
Microsoft has about 150 apps in the Google Play Store, but Outlook still isn't among the five Microsoft Android apps that have over a billion downloads.
Word, Excel, PowerPoint, OneDrive, and Skype have one billion installs apiece, while Microsoft's SwiftKey keyboard has over 500 million. Google counts over two billion Android devices that connect to the Play Store.
Outlook for Android install numbers should continue to rise in future thanks to Office Mobile being preinstalled on devices like Samsung's Galaxy Note 10, which is leading Microsoft's push to bridge Windows 10 with Android via the Your Phone app. Office Mobile will surely be preinstalled on Microsoft's forthcoming Android Surface Duo smartphone, too.
The latest stage of Microsoft's mobile strategy is the Office Mobile app, which offers Android and iOS users lightweight versions of its Office apps, including Outlook.
Having initially limited the app to the Galaxy Note 10, the company in November began offering it to more Android users and iOS users. The single app offers basic viewing and editing features. Users who want richer features can get separate Office apps for their devices by purchasing an Office 365 subscription.
