Configuring the mail flow settings of an Exchange Online mailbox
You can set up rules for the emails that Exchange Online mailboxes send or receive in the organization with the Exchange Online Properties > Mail Flow Settings tab of the Active Roles Web Interface. Active Roles supports setting up two types of such rules:
