How it works…

Look for…

Join a group

Groups are a great way to get work done with a team or to stay informed about a topic. The All Company Group is the default group everyone posts into—you’re automatically part of this group. You can join any public group, but need to be invited to a private group. Click Groups link to find groups you want to join or to create a new group. Click the + to create a new public or private group.

Follow someone

When you follow someone on Yammer it means you want to see messages from them in your feed. You can search for people by name using the search box, or you can scroll through the All Company feed and follow someone that’s posting about things that interest you.

Like someone’s message

When you Like a message, the person who posted the message will receive a notification that you liked it. Use likes to indicate agreement with an idea, acknowledgment that you’ve seen a message, or just to let someone know you like what they’re saying.

Reply to a conversation

Replying to messages is a core part of what makes Yammer useful. When you reply to a message, Yammer starts a thread. That makes it easier to keep track of what everyone is saying. To reply to a message, click Reply under the message and a reply box will appear.

Check your Inbox

Your Inbox is a single place for you to view, prioritize, and manage all of the conversations that are most relevant to you on Yammer. Your Inbox contains the messages that you are following. That includes private messages, announcements, and conversations you have participated in or have been @mentioned in. You can also choose to follow any conversation you wish by selecting the More icon More icon (...) and choosing Follow in Inbox.

Join the conversation

The feed is your information hub. There are three feed views that you can toggle between:

  • Discovery    This is a feed of the conversations most relevant to you, based on what you subscribe to and your interactions with Yammer network content.

  • All    These are all the conversations to which you have access within your company network.

  • Following    These are the conversations you actively subscribe to, including conversations that your followers have participated in or liked and conversations that have been tagged with a topic you follow.


To view your groups' conversations, use the left navigation and go directly to the group to see new conversations in your groups. When you're all caught up, click the group-to-group transition link at the bottom of your feed to go to your next groups' new conversations.
