This domain is a subdomain of office.net, owned by Microsoft, but it's not a real consumer website. The SSL certificate is issued for a different Microsoft service (Skype) and doesn't match, so your browser will block the connection. The site returns a 404 error and has no content, contact info, or legal pages. Legitimate Microsoft services use proper certificates and are fully accessible. This looks like a misconfigured internal test endpoint that shouldn't be used by anyone. If you're looking for a Microsoft product or service, go directly to the official site. There's no reason to interact with this address, and you won't be able to anyway. It's not a scam, but it's also not a website you can trust to do anything useful.

Where the score comes from
We look at six areas. Here's how callcontroller.maso-04.ic3-calling-callcontroller.malaysiasouth-prod.cosmic.office.net did in each.
10
Security
The SSL certificate is invalid and the site is unreachable due to a TLS error. This is a critical failure for any website, but especially for one that might be expected to handle data.
35
Identity
The domain is a subdomain of office.net (Microsoft), but there is no direct confirmation of ownership. The WHOIS shows no match, and the certificate is for a different Microsoft service, adding confusion.
50
Reputation
No blacklists or threat detections, but the site has no web archive history and is not ranked. This is neutral for a non-public endpoint, but gives no positive signals.
80
Transparency
Missing contact info and about page is completely normal for an internal infrastructure endpoint. No transparency is expected here.
80
Compliance
No privacy policy or terms of service exist, but that's standard for a service that isn't intended for consumer use. No compliance obligations apply.
40
Infrastructure
DNS resolves and the site is hosted on Microsoft's network, but it returns a 404 error and is unreachable. No email or security headers are set, which is typical for a test or misconfigured service.
