Configure email forwarding in Office 365

Configure email forwarding

Before you set up email forwarding, note the following:

  • Once you set up email forwarding, only new emails sent to the from mailbox will be fowarded.

  • Email forwarding requires that the from account has a license. If you're setting up email forwarding because the user has left your organization, another option is to convert their mailbox to a shared mailbox. This way several people can access it. However, a shared mailbox cannot exceed 50GB.

You must have admin permissions in Office 365 to do these steps.

Use the new admin center to configure email forwarding

The new admin center is available to all Microsoft 365 admins. You can opt in by selecting the Try the new admin center toggle located at the top of the Home page. For more information, see About the new Microsoft 365 admin center.

  2. Select the name of the user whose email you want to forward to open the properties page.

  3. On the Mail tab, select Manage email forwarding.

    To forward to multiple email addresses, you can ask the user to set up a rule in Outlook to forward to the addresses. To learn more, see Use rules to automatically forward messages.
