Last updated on April 14th, 2021

This tutorial contains detailed instructions on how to create and setup a shared mailbox in Office 365 and how to give access to users on the shared mailbox. In Office 365, shared mailboxes don't require a license and can't be added in Outlook for desktop or in Outlook for Web as an independent mailbox.

A shared mailbox allows a company's team (e.g. the 'Sales' team), to have a central email address (e.g. "'), where team members can receive and reply to emails from other employers or customers of the company.

In fact, a shared mailbox can be used from multiple people that belongs to the same group (e.g. the 'Sales' group), to monitor and to respond to e-mails received through the public email alias (e.g. ''). This means that when a user from the group, sends or responds to a new message from the shared mailbox, it sends its message using the public e-mail alias (e.g. ''), instead of his personal email address
