Open and use a shared mailbox in Outlook

A shared mailbox makes it easy for a group of people to monitor and send email from a public email alias like info@example.com. When a person in the group replies to a message sent to the shared mailbox, the email appears to be from the shared address, not from the individual user. You can also use the shared mailbox as a shared team calendar. A shared mailbox is also suitable for use as a "noreply" email account.

TIP: A shared mailbox isn't designed for anyone who's sharing the mailbox to sign in directly to the account. The account for the shared mailbox itself should stay in a disabled state.

Before you can use a shared mailbox, the Microsoft 365 admin for your organization has to create it and add you as a member. For more information, see Create a shared mailbox, which describes what the admin needs to do.

add members (users) to the shared mailbox
