This isn't a typical website you'd visit for shopping or information. It's a subdomain under Microsoft's office.net, but it's not functioning as a public service. The site is completely unreachable, returns a 404 error, and its SSL certificate doesn't match the hostname — it was issued for a different Skype service. There's no content, no contact information, and no legal pages. For a consumer, there's nothing here to trust or use. If you encounter this URL, it's likely a misconfigured or abandoned internal endpoint. Treat it as a broken link and avoid clicking. There's no evidence of a scam, but also no reason to ever visit this address. The only safe move is to stay away.

15/ 100 trust score
In plain English
This is not a trustworthy website. It's a broken internal Microsoft service endpoint that's unreachable, returns a 404 error, and has an invalid SSL certificate. Don't visit or share this URL — it's not meant for public access and offers no useful content or security.
What you should do now
Don't panic. These steps limit the damage, and the sooner you take them the better.

Especially if you got here from an email, text message or social media ad.
3
Already paid? Call your bank

Where the score comes from
We look at six areas. Here's how cpx-enterpriseproxy-2.d03-058.ic3-calling-enterpriseproxy.01-eastus-prod.cosmic.office.net did in each.
10
Security
The SSL certificate is invalid for this hostname and the site is unreachable. That's a serious red flag for any kind of website, even a technical endpoint.
40
Identity
The domain office.net is owned by Microsoft, but this subdomain has no visible ownership or registration info. Without a clear operator, you can't verify who's responsible.
50
Reputation
No blacklists or threat warnings, but there's also no history in the Wayback Machine or any ranking. It's essentially a blank slate with no record to assess.
10
Transparency
There's no about page, contact info, or social media presence. For any kind of publicly accessible service, that's a major gap.
60
Compliance
Missing legal pages are normal for a technical infrastructure endpoint that isn't aimed at consumers. No compliance obligations here.
30
Infrastructure
DNS resolves to Microsoft's network, but the site itself is unreachable with a 404 error. No email setup, no security headers, and no DNSSEC — it's not properly configured for public use.
