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@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. In classic Outlook, you can also use the shared mailbox as a shared team calendar.

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.
Tip: 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.
