How to Add a Shared Mailbox in Outlook (Easy Guide)

If you want to add a shared mailbox in Outlook, you can access it through your Outlook account once permission has been granted by your organization’s administrator. A shared mailbox allows multiple users to read and send emails from the same address without needing separate login credentials.

Shared mailboxes are commonly used in workplaces for managing team email addresses such as support, sales, or helpdesk accounts. This guide explains how to add and use a shared mailbox in Outlook.

What Is a Shared Mailbox in Outlook?

Shared mailboxes are often used for:

Users with permission can open and manage the mailbox directly in Outlook.
