Hello
You can use a mail flow rule in Exchange to add a disclaimer to the bottom of email messages. To avoid multiple disclaimers being added in an email conversation, you can add an exception that looks for unique text in your disclaimer. This ensures that the disclaimer is only added to the original message.
Here’s how you can create a mail flow rule to add a disclaimer to the bottom of email messages:
- In the Exchange admin center, go to Mail flow > Rules.
- On the Rules page, click Add a rule, and then select Apply disclaimers.
- Follow the instructions to create a new rule that adds the disclaimer to the bottom of email messages.
- To avoid multiple disclaimers being added in an email conversation, add an exception that looks for unique text in your disclaimer.
You can also use Exchange Online PowerShell to create the disclaimer rule using the New-TransportRule cmdlet.
