Good afternoon, everyone. I have a client that has a three-person office, all using Office 365. They have never used Yammer, nor do they want to use Yammer. Despite that, they are getting many Yammer emails even after I have removed the Yammer license on each person's account in the admin panel. Is there a better way to turn off Yammer completely? After some Googling, I could not find a definitive answer other than unsubscribing, which was the first thing they did before I shut it off in the admin panel. Any advice or insight would be greatly appreciated.
