Is microsoft365.com legit or a scam?
Official Microsoft 365 sign-in domain owned by Microsoft Corporation since 2010, with valid SSL and clean reputation across major blocklists.
Analysis Summary
MT Intelligence
The domain microsoft365.com is registered to Microsoft Corporation at their Redmond headquarters and has been in continuous operation since April 2010. Our evidence confirms this is the legitimate sign-in portal explicitly referenced in official Microsoft support documentation for accessing Microsoft 365 apps, Copilot, and web versions of productivity tools. The page title and meta description align with Microsoft's official branding. One antivirus engine flagged it as malicious, but this appears to be a false positive — likely triggered by generic keyword matching against the high volume of phishing campaigns that impersonate Microsoft 365 login pages. The domain carries valid Microsoft-issued SSL, ranks in the global top-100k, and has no scam reports, complaints, or negative reviews in public sources. The hosting IP shows a low abuse score of 11/100 with only 10 historical reports, consistent with a major cloud provider's infrastructure.

Still, stay alert
No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.
- Double-check the exact URL in your address bar
Confirm you are actually on microsoft365.com and not a lookalike like m-icrosoft365.com.com or an IDN homoglyph.
- Use a password manager
Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.
