  • Not to the message itself.

    see:

    https://docs.microsoft.com/en-us/exchange/policy-and-compliance/mail-flow-rules/signatures?view=exchserver-2019

    Exchange can't modify the content of some messages (for example, encrypted messages). For rules that add disclaimers to messages, you need to specify what to do if the disclaimer can't be added. This is known as the fallback option for the disclaimer rule. The available fallback options are:

    • Wrap: The original message is wrapped in a new message envelope, and the disclaimer text is inserted into the new message. This is the default value.

      • Subsequent mail flow rules are applied to the new message envelope, not to the original message. Therefore, configure these rules with a lower priority than other rules.

      • If the original message can't be wrapped in a new message envelope, the original message isn't delivered. The message is returned to the sender in an non-delivery report (also known as an NDR or bounce message).

    • Ignore: The rule is ignored and the message is delivered without the disclaimer

    • Reject: The message is returned to the sender in an NDR.

    In the EAC, you select the fallback option in the rule action. In the Exchange Management Shell, you use the ApplyHtmlDisclaimerFallbackAction parameter.

  • Scenario is to setup disclaimer for the outbound mails to External Recipients.

    We have enabled the O365 Message Encryption and RMS Protected messages for outbound mails.

    For in the transport rule Fall back settings, do we need to select wrap or ignore option?

    Also we are not using S\MIME encryption in our environment.

    Depends. If you want to ensure the disclaimer is always applied, use the WRAP option that will create a new message with the disclaimer applied and the original message inserted in it. The recipient will then need to open that inserted message to read the original message sent.

    If you don't mind that the disclaimer is not applied to encrypted messages, use the Ignore option and it will *not* touch those encrypted messages, nor WRAP them in a new message.
