Set Up a Shared Mailbox in Microsoft 365 Admin Center

A shared mailbox allows multiple users to read and send email messages from a common address without requiring a separate user license.

By configuring a shared mailbox, your customer service team can collaborate on incoming inquiries from a single email address. The mailbox relies on the licenses of the users accessing it, avoiding additional monthly costs as long as you stay within the Microsoft licensing limits (typically 50 GB of storage for unassigned shared mailboxes).

Access the Admin Center

Navigate to Shared Mailboxes

In the left-hand navigation pane, click on 'Teams & Groups' to expand the menu, and then select 'Shared mailboxes'.

Create the Mailbox

Click the 'Add a shared mailbox' button. Enter a display name (e.g., Customer Service) and specify the desired email address prefix (e.g., support or info).

Save Changes

Click 'Save changes' to generate the new shared mailbox on your domain.

Assign Permissions

Under 'Next steps' on the confirmation screen, click 'Add members to this mailbox'. Select the licensed users who need access, and ensure they are granted both 'Read and manage' and 'Send as' permissions.
