If you're still using Skype for Business, Microsoft Teams, or Yammer with a Windows phone, you'll want to start finding an alternative soon. Microsoft has announced that all three Windows phone apps will be retired on May 20, only leaving users the option of using them in a web browser or switching platforms (via MSPU).
From Microsoft:
Effective May 20, 2018, the Windows Phone apps for Skype for Business, Microsoft Teams, and Yammer will be retired. Starting on that date, these apps will no longer be available for download from Microsoft Store, and Microsoft will no longer support them.While Microsoft continues to support Windows 10 Mobile, we are not focused on building new features for the system. We will continue to invest in the Skype for Business, Microsoft Teams, and Yammer mobile apps for iOS and Android, and also in desktop apps for Windows and Mac.
While the apps may continue to work if you already have them installed, the lack of future updates virtually guarantees that you'll encounter issues down the road.
Given the state of Windows 10 Mobile, this move isn't entirely surprising. And while using the services in a mobile browser may work for some, moving to Android or iOS, where the native apps are consistently updated with new features, would provide a better experience.
The move comes as Microsoft is also in the process of migrating Skype for Business users to Microsoft Teams.
