I want to remove the Yammer app now that authentication is going via Office365. Simply clicking deactivate does not seem to remove the app from users' screens and is causing confusion. I can't seem to see a way to bulk remove/deprovision users (I have over 100, am sure many companies have more but 100 is enough for me not to want to do this on an individual basis). Am I missing something? Please point me in the right direction. Thanks
Once the app is deactivated, the users should be deprovisioned from the app. Since they were not, you could reactivate the app and then deprovision the users/groups assigned to the app and then deactivate the app.
