• ✗

  Create a mail flow rule in the EAC in Exchange Online. Set the rule to apply to messages sent to 'Outside the organization'. Add a condition 'The sender is located' and select 'Inside the organization'. Add an action to prepend a disclaimer. Then create a second rule that applies to messages sent from on-premises mailboxes using a header condition, and block the first rule.

  Why it's wrong here

  This approach is overly complex and unnecessary. The first rule already correctly identifies messages from inside the organization (which includes on-premises mailboxes) to outside recipients. Adding a second rule with a header condition and blocking the first rule would not only be redundant but could also prevent the disclaimer from being applied if the header condition is not met. The requirement is simply to apply the disclaimer to messages from on-premises to external, which the first rule achieves without additional rules. This option introduces unnecessary complexity and potential failure points.

• ✗

  Create a mail flow rule in the EAC on the on-premises Exchange Server. Set the rule to apply to messages sent to 'Outside the organization'. Add an action to prepend a disclaimer. Enable the rule.

  Why it's wrong here

  While you can create mail flow rules on-premises, the requirement is to ensure the disclaimer is applied to messages sent from on-premises mailboxes to external recipients. However, in a hybrid deployment, mail flow rules on-premises may not be applied if the message is routed through Exchange Online. Additionally, the scenario implies using Exchange Online rules for centralized management. On-premises rules can be bypassed if mail is sent directly from Exchange Online or if the on-premises server is not in the routing path. The most reliable method is to create the rule in Exchange Online, which sees all mail flow in a hybrid configuration.

  Create a mail flow rule in the EAC in Exchange Online. Set the rule to apply to messages sent to 'Outside the organization'. Add a condition 'The sender is located' and select 'Inside the organization'. Add an action to prepend a disclaimer. Enable the rule.

  Why this is correct

  In a hybrid deployment, on-premises mailboxes are treated as 'Inside the organization' by Exchange Online. Therefore, a rule that applies to messages sent to 'Outside the organization' and has a condition that the sender is located 'Inside the organization' will correctly match messages sent from on-premises mailboxes to external recipients. The action to prepend a disclaimer will add the disclaimer to those messages. This configuration meets the requirement precisely and is the standard method for applying disclaimers to outbound mail from on-premises senders in a hybrid setup.

• ✗

  Create a mail flow rule in the Exchange admin center (EAC) in Exchange Online. Set the rule to apply to messages sent to 'Outside the organization'. Add a condition 'The sender is located' and select 'Outside the organization'. Add an action to prepend a disclaimer. Enable the rule.

  Why it's wrong here

  This rule applies to messages sent to outside the organization and from senders located outside the organization. However, senders located outside the organization would be external senders, not on-premises mailboxes. On-premises mailboxes are considered 'Inside the organization' in Exchange Online because they are part of the same Exchange organization in a hybrid deployment. The condition 'The sender is located' with 'Outside the organization' would not match on-premises senders, so the disclaimer would not be applied to the intended messages. This rule would incorrectly target inbound external mail.
