The Windows Phone app for Yammer is scheduled to be retired. After this change takes effect, this app will no longer be available for download from Microsoft Store, and Microsoft will no longer provide support.
Although we continue to support Windows 10 Mobile, we are not focused on building new features for the system. We will continue to invest in Yammer mobile apps for iOS and Android and in desktop apps for Windows and Mac.
How does this affect me?
After May 20, 2018, the Yammer app for Windows Phone will no longer be available from the Microsoft Store. The Yammer app may continue to work, but this is not guaranteed. The Yammer app will no longer receive updates or support.
What do I have to do to prepare for this change?
Users can access Yammer by using the mobile browser.
