From 18 September onwards, Microsoft will stop supporting Office and Outlook for Android Apps on Chrome OS. The apps will not be available on Google Play Store anymore and instead, users will have to sign in to through the web via Office.com or Outlook.com.
About Chromebooks' Kevin Tofel pointed out that the new move may be disappointing as he couldn't open existing documents using Microsoft’s progressive web app for Chrome OS while offline. This could be a major turn-off for many users who rely on the Play Store version.
“In an effort to provide the most optimized experience for Chrome OS/Chromebook customers, Microsoft apps (Office and Outlook) will be transitioned to web experiences (Office.com and Outlook.com) on September 18, 2021. This transition brings Chrome OS/Chromebook customers access to additional and premium features. Customers will need to sign in with their personal Microsoft Account or account associated with their Microsoft 365 subscription. More information is available here.”
The company hasn't made any comments about the missing offline functionality or whether improvements would be made before the new change takes over next month.
