Leave or unsubscribe from a group in Outlook

When you leave a group, you give up your access to the group inbox, calendar, OneNote notebook, and library. The only way to regain access is to rejoin the group.

When you unsubscribe from a group (Outlook 2016 only), you are still a member but no longer receive messages and calendar event notifications in your personal inbox. You'll have to go to the group inbox to see them.

  1. Open Outlook on the web.

  2. In the navigation pane, under Groups, select your group.

  3. In the group header, select Settings button in groups > Leave group. You'll no longer be a part of the group and won't be able to access the files or other data.

As a guest, you receive all group conversations in your inbox; you don't have a group mailbox in your email client. In every email conversation you'll see a message with a link to leave the group.

Message presented to guests in each mail received from the group

Click the link to leave the group. You'll receive a message asking you to confirm that you want to leave.

Once you confirm, you'll receive an email that includes a link to rejoin. Clicking the link will send a request to the group owner.

    • Unsubscribe    You'll still be a part of the group, but won't receive any conversations or invitations in your inbox, except in these two cases:

      • When someone replies to a message that was sent to the group by an unsubscribed user, the unsubscribed user receives those messages in his or her inbox.

      • When someone replies to a message that was replied to by the unsubscribed user, the unsubscribed user receives those messages in his or her inbox.

    • Leave    You'll no longer be a part of the group and won't be able to access the files or other data.
