Open and use a shared mailbox in Outlook

Open and use a shared mailbox in Outlook

Last updated 15 July, 2019

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.

A shared mailbox is not designed for direct log on though. The user account for the shared mailbox itself should stay in disabled state.

Tip: Before you can use a shared mailbox, the Office 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.

Add a shared mailbox to Outlook

After your admin has added you as a member of a shared mailbox, close and then restart Outlook. The shared mailbox should automatically display in your Folder pane in Outlook.

What if it didn't work?

  • If that didn't work, then manually add the shared mailbox to Outlook:

    1. Open Outlook.

    2. Choose the File tab in the ribbon.

    3. Choose Account Settings, then select Account Settings from the menu.
