Question

Block blank emails with external disclaimer on it.

Carlo Angelo Gaton 0

Greetings!

In the Microsoft Defender, we can mark as spam a blank email. But what if there is an external disclaimer for your company? We also don't want to disable the disclaimer for the users to be aware of the external senders.

We tried to block the blank emails with disclaimers by using the (The message size is larger than or equal to '15 KB (15,360 bytes)') in the Transport rule. But I think there were emails that will be affected on this rule.

What can you suggest for the alternatives?

Thank you!

Thank you for posting your query on Microsoft Q&A, I was able to review the possibilities of block emails without any content.

You could achieve this by creating Anti-spam policies:

Hi @Akshay Kaushik ,

Yes, we configured the Anti-spam policy. But we still receive blank emails (blank subject and body) because of the footer from the email. Is it possible to ignore the footer?
