    Hi @Microsoft Q & A

    You can set up a MailTip to appear when internal members send emails to this mail user.


    For specific operations, please refer to the following:

    1.      In the Exchange admin center , open Recipients-Contacts

    2.      Click Specify mail user account

    3.      Click Manage Mail tip under General

    4.      Set the text and save

    User's image

    User's image

    You can also refer to this command to modify mail tips for all mail users in bulk:

    Get-mailuser|set-mailuser -mailtip “This is a mail user account! Your message will be forward to external!”
