How to use a shared mailbox (Outlook desktop app)
A shared mailbox makes it easy for a group of people to monitor and send email from a public email alias like info@contoso.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.
Before you can use a shared mailbox, the Office 365 admin for your organization has to create it and add you as a member.
