Microsoft has a number of different versions of its Office apps in market. There's the Win32 version of Office, the web/online version of Office (referred to, these days, as Office.com apps) and a Universal Windows Platform (UWP), touch-enabled version of Office called Office Mobile. There are also versions of the Office apps for iOS and Android.
When I asked Microsoft if the company was putting Office Mobile for Windows on the back burner, a spokesperson confirmed the move with the following statement:
"The Office mobile apps for Windows have not been deprecated. But for mobile, we are currently prioritizing development for the iOS and Android versions of our apps; and on Windows, we are prioritizing Win32 and web versions of our apps."
The decision to deprioritize Office Mobile on Windows is definitely closely linked to Microsoft's decision to step away from Windows Mobile. But it also likely has to do with the growing acknowledgement by many inside and outside the company that the original UWP strategy has not been successful. Microsoft has been introducing ways to bring Win32 and Progressive Web Apps (PWA) to its Microsoft Store, alongside "pure" UWP apps.
On Windows, Microsoft is actively encouraging users on devices with screens of all sizes to opt to subscribe to Office 365 in order to use its Office apps. And maybe there will be PWA version of many/most/all of the Office apps in the not-too-distant future, too?
