Hi,
Since there is a detection from Email Defender, it is possible that the content of the email is malicious.
If you really want to turn off the feature, you may disable it temporarily, but it is recommended to enable it again for your protection. Kindly check our help center guide below on how to Turn OFF/ON the feature.
You may also check Secure Your Gmail, Yahoo, and Outlook Mail with Email Defender to know more on how Email Defender works.
Hope this helps!
