This address is a subdomain of Microsoft's own network, but something has gone wrong. The SSL certificate is issued for a different hostname, so your browser won't let you connect securely. The homepage shows a generic 'services not available' message, which confirms the site isn't working as intended. For a typical Microsoft service endpoint, you'd expect a valid certificate and a working status page. Here, you get neither. This isn't a phishing site or a scam — it's more likely a misconfigured internal URL that leaked somewhere. But the practical result is the same: don't try to use it. You can't complete any action because the connection fails. If you came here expecting an Office or Microsoft service, double-check the link you followed. Legitimate Microsoft services use verified certificates and proper domain names like office.com or login.microsoftonline.com. This URL isn't one of them.
No — mss-office-com.b-0005.b-msedge.net doesn't look safe
In plain English
This URL is broken, not a functional website. The SSL certificate error means you can't safely reach the intended content. It looks like a misconfigured Microsoft CDN endpoint, not a scam, but there's nothing here for a visitor to trust or use.
What you should do now
Don't panic. These steps limit the damage, and the sooner you take them the better.
Don't enter any details
No passwords, card numbers or personal information — even if the site looks professional.
Close the tab
Especially if you got here from an email, text message or social media ad.
Already paid? Call your bank
Contact your bank or card provider right away. They can often stop or reverse a recent payment.
Warn others
Report the site and share this check with anyone who sent you the link.
Where the score comes from
The SSL certificate is invalid and the site is unreachable due to a hostname mismatch. You can't establish a secure connection, which is a hard stop for any site that expects visitors.
This is a subdomain of msedge.net, which is owned by Microsoft. The domain itself doesn't resolve in WHOIS, but the parent is a known entity. No hidden ownership concerns here — just an opaque subdomain naming.
The site has no history in the Wayback Machine, no search traffic, and no external reviews. It's either brand new or simply not meant for public browsing. Nothing malicious detected, but also no track record.
There's no about page, contact info, or social media presence. But this is a technical service endpoint — not a business trying to win customers. The lack of transparency is expected for a backend URL.
No privacy policy or terms of service are present, which is normal for a non-commercial infrastructure hostname. There's no data collection or interaction happening here.
The domain resolves to a Microsoft IP and is hosted on Microsoft's network, but it lacks basic security headers, DNSSEC, and email handling. More importantly, it can't serve its intended content because of the SSL mismatch.
