Question details

Determine how to set up role-based or departmental business email addresses (such as info@, applications@, and events@) without purchasing separate Microsoft 365 licenses for each.

How to Use Generic Business Email Addresses Without Individual Microsoft 365 Licenses

Product: Microsoft 365
Device & OS: not provided
Scenario: Setting up generic company email addresses for different departments or functions while employees already have their own licensed mailboxes.
Observed behavior: Needs to configure addresses like info@ and applications@ and receive emails without incurring extra individual licensing costs.

Before you start

Ensure you have Microsoft 365 global admin or Exchange admin permissions to configure recipient types, and confirm that the users who will access these addresses already hold active Microsoft 365 licenses.

Solution 1Recommended

Configure a Shared Mailbox

Shared mailboxes are ideal when multiple people need access to a generic email address, such as info@ or sales@, and they do not require a separate license.

A shared mailbox functions like a standard mailbox but doesn't have its own login credentials. Licensed users are granted access to open it, read emails, and send replies on behalf of the shared address.

Access the Admin Center

Create the Shared Mailbox

Navigate to Teams & groups, select Shared mailboxes, and click 'Add a shared mailbox'. Enter a name and the desired email address (e.g., info@yourdomain.com).

Assign Members

Once created, select the mailbox and click 'Edit' under the Members section. Add the existing licensed employees who need to monitor and reply from this address.

Storage Limits: A shared mailbox does not require a license as long as its total storage remains under 50 GB. If it exceeds 50 GB, an Exchange Online Plan 2 license must be assigned.

Solution 2

Add an Email Alias to an Existing User

If only one specific employee needs to receive emails sent to a generic address, you can add it as an alias to their existing mailbox at no extra cost.

Solution 3

Keep Addresses Hosted Outside Microsoft 365

If you already use a third-party email host for specific domain addresses, they can remain external without needing any Microsoft 365 licensing.

Frequently Asked Questions

Do Microsoft 365 distribution groups require a separate license?

No. Distribution groups, which send incoming emails to a list of specified members, are free to create in Microsoft 365 and do not require individual licenses.

Can a shared mailbox have its own password?

By design, shared mailboxes do not have passwords. Users cannot log in to a shared mailbox directly; instead, they must sign in to their own licensed Microsoft 365 account and access the shared mailbox via delegation.

What happens if a free shared mailbox exceeds its 50 GB storage limit?

If a shared mailbox exceeds the 50 GB limit, you will no longer be able to send or receive messages from it. To expand the storage to 100 GB, you must assign an Exchange Online Plan 2 license to the shared mailbox.

Are mail-enabled contacts licensed in Microsoft 365?

No. Mail-enabled contacts simply contain information about people outside your Exchange organization and appear in your global address list. They do not hold mailboxes and therefore do not require any licenses.
