Once setup O365 Anti-spam [new Microsoft 365 Defender] what is the best way to test it?
Best practice, avoiding to expose the users too much, using specific tools, creating false email spam , trace, etc ...

Thanks

    Hi @Marc

    Agree with the suggestions above from Andy.

    Use the Generic Test for Unsolicited Bulk Email (GTUBE). It's a standardized spam signature used precisely for testing spam filters.

    Put this in the body of the test email:

    XJS*C4JDBQADN1.NSBN3*2IDNENGTUBE-STANDARD-ANTI-UBE-TEST-EMAILC.34X
    and it will force the mailb to be recognized as spam.

    In addition to the spam, the official document also provided a way to Simulate a phishing attack. You could refer to this if you need.
