Tricityelectric.sharepoint.com is a Microsoft SharePoint site, not a typical public business website. It redirects visitors to a Microsoft login page, which is exactly what you'd expect from a corporate document-sharing platform. Employees or authorized users access it through their company credentials, and the site isn't meant for the general public. This explains the lack of public web archive history, Trustpilot reviews, and search engine ranking.
Most legitimate SharePoint sites behave the same way: they block search crawlers, don't have public sitemaps, and exist only behind a login. The technical signals here are strong: a valid SSL certificate from Microsoft, HSTS enforcement, and clean security checks across multiple databases.
If you are an employee of Tricity Electric and have been directed to this site, you can trust that it's the real Microsoft platform handling your authentication. For anyone else, there's nothing to interact with publicly. The site does what it's supposed to do without raising any red flags.
