Question details

A company wants to maintain several business email addresses without paying for and assigning Microsoft 365 licenses to each of them, while keeping licensed Microsoft 365 Business Standard accounts for core users.

Product: Microsoft 365
Device & OS: not provided
Scenario: Optimizing subscription costs by managing company email addresses independently from the paid Microsoft 365 licensing environment.
Observed behavior: Seeking ways to retain functional business email communication for specific addresses without triggering the requirement for additional Microsoft 365 user licenses.

Before you start

Before making changes to your licensing, verify where your domain's MX records are currently pointing and determine if the affected email addresses require access to Microsoft 365 services like OneDrive or SharePoint.

Solution 1Recommended

Host the Email Address with a Separate Third-Party Provider

You can host specific email addresses outside of Microsoft 365 using a different, often more cost-effective, email hosting service while keeping Microsoft 365 for your core users.

If an email address is not actively tied to a Microsoft 365 account and operates through a separate email hosting service, it does not require a Microsoft 365 license. This setup, often called split-domain routing, allows a company to manage budget efficiently.

Set up the external mailbox

Create the desired business email addresses on your third-party email provider's platform (e.g., standard cPanel webmail, Google Workspace, or Titan).

Configure mail routing in Exchange

Log in to the Microsoft 365 Exchange admin center. Set up connectors to properly route emails between the licensed Microsoft 365 users and the external mailboxes.

Update domain routing

Ensure your domain registrar allows split-domain routing and update your DNS settings to ensure external servers know where to deliver incoming mail for the un-licensed addresses.

Solution 2

Convert to a Microsoft 365 Shared Mailbox

If the email address does not require a dedicated user login and is only used to receive or send emails (such as info@ or support@), you can use a free Shared Mailbox.

Frequently Asked Questions

Do I need a Microsoft 365 license for an 'info@' or 'sales@' email address?

No, you do not need a paid license for generic company addresses if you set them up as Shared Mailboxes in the Microsoft 365 Admin Center. Existing licensed users can access and manage these shared mailboxes for free.

Can I mix Microsoft 365 accounts with other email providers on the same domain?

Yes. This configuration is known as split-domain routing. You can set up your Exchange Online connectors and domain DNS to route emails for specific users to a third-party email provider, avoiding Microsoft 365 license costs for those users.

What happens to a user's emails if I remove their Microsoft 365 license?

If you remove a user's license without backing up their data or converting their account to a shared mailbox first, their mailbox data is held for 30 days and then permanently deleted.

Is it legal to share one Microsoft 365 licensed account among multiple users?

Microsoft's terms of service require each individual human user to have their own dedicated license. Sharing a single user login (e.g., sharing a password) across multiple employees violates the licensing agreement and compromises security.
