If you receive a notification about Yammer conversations in OWA, you might notice that you can now do all sorts of new things to interact with Yammer while remaining in OWA. It’s part of Microsoft’s effort to make Yammer more relevant and accessible to people who prefer to communicate through email. And the nice thing is that the approach works well.
Teams is all about open communication, but sometimes you just want to make a statement and not have a conversation. You can do this by restricting replies to a topic, in which case only the original author and channel moderators can reply. And if moderation isn’t used for a channel, team owners take that role.
