If you've landed on obe0.sharepoint.com, you're looking at a Microsoft SharePoint site. That means it's part of a widely used business collaboration platform, not a standalone website. The site immediately redirects to a Microsoft login page, which is exactly what you'd expect for a SharePoint site that requires authentication.
Most legitimate SharePoint sites behave this way: they block search engine crawlers, don't have public contact pages, and rely on Microsoft's security infrastructure. The domain is a subdomain of sharepoint.com, which is owned by Microsoft, a company with a long track record. The site uses modern encryption and has no history of malware or blacklisting.
If you're trying to access this site as part of your work or school, you can be confident it's the real thing. There's no evidence of fraud or deception here. The only thing to watch for is whether you trust the organization that gave you the link, since SharePoint sites are often used for internal company files. But the platform itself is safe.
