Maliciousness Score: 2/10 (Likely Legitimate but Requires Caution) ✅ Positive Indicators: Return-Path matches sender domain (microsoft.com). Received header shows Microsoft’s IP range (40.92.75.10, belongs to Microsoft). SPF, DKIM, and DMARC all pass (indicating proper authentication). Legitimate Microsoft Message-ID format. 🚩 Potential Warning Flags: Unexpected security alert—if the recipient did not expect this email, it could be a phishing attempt. Generic sender ("Microsoft Security Team")—real Microsoft alerts usually include more context. Check for suspicious links—hover over any links in the email to ensure they point to official Microsoft domains. 🔎 Recommendation: If you recently attempted to log in, verify through your Microsoft account (not via email links). If unsure, check Microsoft's security center directly. DO NOT click links or download attachments before verifying legitimacy.
