1. Open Outlook on the web.
2. In the navigation pane, under Groups, select Discover. (If you don’t see Discover, click More at the bottom of your groups list. Once all of your groups are displayed you should see the Discover link.)
3. All available groups will be listed in alphabetical order. Select the one you want and click Join. If the group is public, you’ll see a confirmation message and become a member right away. If the group is private, type a reason why you want to join > Send.

   TIPS:

   • How do you know at a glance whether a group is private? It’s noted at the top of the group card, as in this example.
   • 

   Once you’ve joined a group you’ll receive a welcome message that contains important information and links to help you get started. If the group is public, you’ll get the message right away. If the group is private, you’ll get the welcome message after you’ve been approved by group owner.

Invite others to join a group

1. Open Outlook on the web.
2. On the left navigation pane, select the group you want to invite others to join. You can only invite people from your school or organization. If you want to invite a guest user from outside your organization, you’ll have to use the add/remove process. See Add guests to a group for instructions.
3. Do one of the following:
   • On the menu bar, select More group actions > Invite others.
   • At the top of the page, select the name of the group, and select More actions > Invite others.
4. Do one of the following:
   • Select Copy to copy a link to the group to your clipboard. Paste the link into a message to share it with others.
   • Select Email to open a compose window with a link to join the group.
