Conversations in a Microsoft 365 Group in Outlook happen in the shared inbox for the group. You can read and reply to messages, and members can easily search or scroll back through the message history to get caught up on what's been discussed before. Members who join or follow Groups in Outlook also receive conversations in their personal inbox. 

Here are a few important things to remember about sending emails to a Group in Outlook:

  • Anyone in your organization can start a group conversation.

  • For a public group, anyone in your organization can read and respond to the group's conversations.

  • For a private group, only group members can participate in the conversation.

  • If you delete group email from your personal inbox, the email can still be found in the group mailbox.

Note: These features are only available to individuals using a work or school account with a qualifying Microsoft 365 subscription.
