If you've come across 201294-ipv4v6.farm.dprodmgd108.aa-rt.sharepoint.com, you're likely dealing with a misconfigured internal server rather than a public website. This hostname sits under Microsoft's sharepoint.com domain, but the SSL certificate doesn't match β meaning your browser won't let you connect securely. That alone is a dealbreaker for any kind of safe browsing.
There's no homepage, no contact information, and no legal pages. That makes sense because this isn't a business trying to sell you something. It's an infrastructure endpoint, probably part of Microsoft's internal network. The lack of a web archive history suggests it's either very new or not meant to be publicly accessible.
For most people, the question of whether it's a scam is moot. You can't use this site for anything, and it's not impersonating a store or service. The real takeaway: if you ever need to connect to a SharePoint server, make sure you have the correct hostname and a valid SSL certificate. This one fails the basic test.
