[Bug][aup] Investigating spoofed self-to-self phishing email in own M365 tenant flagged as policy violation (req_011CcPDtscPq7dauMMzXm3vD)

Type: AUP / Usage-Policy block (false positive) · Work domain (heuristic): cloud-iam

Why this is a false positive

Self-spoofing investigation on an authorized, owned email tenant—where the operator holds admin credentials and is hardening their own anti-spoof posture—was flagged as a policy violation. The work in scope was routine cloud-IAM and mail-security diagnostics: reviewing SPF/DKIM/DMARC alignment, auditing Exchange transport rules, and inspecting message headers in a mailbox the user administers to identify and close the gap that permitted a self-addressed spoof. None of these read-only, defensive administrative actions involve sending deceptive mail, accessing third-party systems, or any disallowed activity, so the block is a false positive on legitimate owner-authorized security work.
