If you've landed on callawaygolfco-my.sharepoint.com, you're looking at a private SharePoint site used by Callaway Golf employees. This isn't a public website selling products or asking for your personal information. It's a corporate collaboration platform hosted on Microsoft's own infrastructure.
Because the site requires authentication, you'll be redirected to a Microsoft login page. That's a normal part of how SharePoint works. The site uses strong encryption, blocks clickjacking, and has no history of malware or blacklisting. The robots.txt file blocks all crawlers, which is standard for internal sites that shouldn't be indexed.
Is callawaygolfco-my.sharepoint.com a scam? No. The domain is a subdomain of sharepoint.com, and the only way to access its content is by logging in with authorized credentials. For those who need to use it, there's no reason to worry about safety. Just make sure you're on the real Microsoft login page and not a lookalike. If you're not a Callaway Golf employee, you won't be able to access anything, and that's by design.
