Select the domain to use for email from Microsoft 365 products

In this article:

Emails sent out to users as they interact with each other and across various products within Microsoft 365 are designed to provide insights and information about their organization. These emails are typically sent out between users based on those interactions, which means that they're often sent from the user’s email address. Those emails will remain unchanged and will continue to work as they do today.

There are several scenarios where emails are sent from a “no-reply” system-based product account. For example, batched comments, news, digests, and system notification emails are currently sent from a no-reply product address. These include addresses such no-reply@sharepointonline.com, no-reply@planner.com, no-reply@project.com.

The default option is that users receive no-reply emails sent by Microsoft on behalf of your organization, which users receive as [EXTERNAL] notifications. You now have the option to use a custom domain as the sender of these notifications. Using this feature means that emails will now be sent from your own Exchange Online instance and they become internal communication. For example, no-reply@sharepointonline.com [External] could become no-reply@contoso.com, if Contoso.com is the domain that has been selected.

Note

Only domains registered within your tenant can be used and ownership must be verified through the existing add domains process within Microsoft 365. Please follow the steps below and note the DNS records required when configuring a domain for sending email.

Configure the "Send email notifications from your domain" setting

The setting is available via the Microsoft 365 Admin Center Settings menu item. Select Settings, select Org settings, and then select the Organization profile tab as illustrated below.

Org Settings - Send email notifications setting

Note

  • This setting is an opt-in setting which allows the Microsoft 365 system administrators to select a verified domain within the tenant. This means that the domain has been validated for ownership.
  • The recommendation is to use a domain that has the appropriate DNS records to facilitate email validation, like SPF, DKIM, DMARC, and MX as this then complies with the RFC compliance for sending and receiving email. Please see Learn more about Exchange Online Email Routing for more information.
  • Please ensure that you comply with all privacy, compliance and security requirements and policies within your organization.

To configure the "Send email notifications from your domain" setting:

  1. In the Microsoft 365 admin center, in the navigation pane select Settings.
  2. Select Org settings.
  3. On the Org settings page, select Organization profile.
  4. On the Organization profile page, select Send email notifications from your domain.
  5. In the Send email notifications from your domain page, select Use a custom send-from domain address.
  6. The Domains menu, select the domain that you want to use for your email replies.The domains listed in the menu includes verified complete and incomplete domains as Microsoft 365 allows DNS settings to be configured and managed outside of the tenant. Your System or Exchange administrator must ensure that they follow and meet all DNS and domain requirements.
  7. For Custom username, administrators can optionally configure the no-reply prefix. They could then create a matching email address in Exchange, if they would like to monitor responses from users.
  8. Select Save. Changes will take a few minutes to complete.

Send email notifications setting.

Note

If you make a mistake or would like to roll-back the change, de-select the Use a custom send-from domain address checkbox and then select Save. The setting will revert to the original configuration.
