Microsoft Defender for Office (MDO) - Customize Results Email for User Reported Messages

Hi all,

I would like to customize the results email from MDO to the users. From the documentation, I can see the option to modify "Email body results text" and "Email footer text":

Microsoft Defender for Office (MDO) documentation about custom results email

Custom notification options in the Defender portal

Unfortunately, the documentation doesn't specify anything beyond that. Therefore, I have the following questions:

• What exactly is the Email "body" and "footer" in this template? (Compare to screenshot below)
• Is the title/header part of the "body"?
• What type of text from is available? (Plain/HTML/Markdown etc.)

Example Email / Default "SPAM" response

Does anyone have experience with customizing these result emails? Feedback would be appreciated, thanks!
