How to Create a Shared Mailbox in Office 365

In shared mailbox, a group of users can send an email from a common email address like [email protected] or [email protected]. They can also read emails when they are sent to that common email address.

In this tutorial, I will show you to create a shared mailbox, add members, send an automatic reply, and forward emails to any other inbox inside or outside the organization when they are actually sent to shared mailbox.

4. Expand Groups and click ‘Shared mailboxes’. Click ‘+ Add a mailbox’.
