In Exchange Online, this process is known as moderation, where a designated approver, or moderator, reviews messages before they are sent. This guide outlines the steps to set up message approval in Exchange Online, ensuring enhanced control over outbound emails, especially during crucial stages like the Halo setup or Go-Live.</p><p><br></p><p id="isPasted"><strong>Step 1: Login to Exchange Admin Center</strong></p><p>Begin by logging into the Exchange Admin Center, the central hub for managing your Exchange Online environment.</p><p><br></p><p><strong>Step 2: Navigate to Mail Flow</strong></p><p>In the Exchange Admin Center, locate and click on the "Mail Flow" option. This is where you'll manage the flow of emails within your organization.</p><p><br></p><p><strong>Step 3: Access the Rules Tab</strong></p><p>Within the Mail Flow section, navigate to the "Rules" tab. Here, you'll create and manage rules that govern the flow and handling of emails.</p><p><br></p><p><strong>Step 4: Create a New Rule - Send Messages to a Moderator</strong></p><p>Click on the option to create a new rule. Choose the rule type related to sending messages to a moderator for approval.</p><p><br></p><p><strong>Step 5: Set the Name of the Rule</strong></p><p>Assign a descriptive name to the rule, making it easy to identify its purpose.</p><p><br></p><p><strong>Step 6: Specify the Rule Conditions</strong></p><p>Under "Apply this rule if," select "The sender." Specify the mailbox you want to moderate. Typically, this will be your support mailbox or the relevant account:</p><p><br></p><p><img src="https://halo.haloservicedesk.com/api/attachment/image?token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6IjUxMjQ2YzJiLTg2NWUtNGUxNS1iZmQ0LTQ2OTk1MTg0ODgzMCJ9.UIx5iUfxL_hTytpxMYEctwDDkWpJxIXNd6bwOPDDiG0" class="fr-fic fr-fil fr-dib" width="502" style="width: 502px; height: 533.435px;" height="533.435"></p><p><br></p><p><strong>Step 7: Define Action - Forward the Message for Approval</strong></p><p>Choose the action for the rule, which is to "Forward the message for approval." This action ensures that messages from the specified sender are sent to the moderator for review:</p><p><img src="https://halo.haloservicedesk.com/api/attachment/image?token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6IjRjZTY1ZTg4LWRiYzktNDM0MS1hYTQ5LWM3ODNjNmZmNDc5OSJ9.v_OKkJPMVIcw5nscceEfyV4CDlwHuozo4ubv_51M2So" width="444" class="fr-fic fr-dii" style="width: 444px; height: 216.308px;" height="216.308"></p><p><br></p><p><strong>Step 8: Set the Moderator's Email Address</strong></p><p>Under "To these people," specify the email address of the moderator. This is the person who will receive the email for approval before it is sent out:</p><p><br></p><p><br></p><p>By following these steps, you've successfully configured message approval in Exchange Online. This moderation setup is particularly useful when introducing new mailboxes, implementing Halo, or ensuring a controlled Go-Live process, offering an added layer of assurance before outbound messages reach their recipients.</p><p><br></p><p>Sometimes it makes sense to have a set of eyes on a message before the message is sent from your mailbox. As an Exchange Online admin, you can set this up. Requiring approval before a message is sent from a mailbox is called moderation, and the approver of the message is called the moderator.</p>
