@gapps.microsoft.com would be at least better than a random unverifiable @gmail.com address. Google Workspace (is that what we're calling it this week?) lets you use subdomains right?

Let's be real: getting legal and infosec to sign off on that is never going to happen. "We just need to borrow a subdomain of Microsoft.com, give control to our biggest competitor, and sign a contract with them... to get a vanity email address in their store."

It's really not that big of a deal. You can still control the DNS and decide what you set up. And if Google screws you over, they'd be shooting themselves in the face.

All you'd need to actually work would be email, so some MX records on a subdomain. Is it ideal? No. Is it better than all of your users having no way to verify that a Chrome extension is actually you? Infinitely better.

opening a gmail account takes about 30 seconds

vs. months of emails and meetings for something that more or less achieves the same result

Except it doesn't more or less achieve the same result. Also, if it legitimately takes months of meetings to get through something like that, there's a serious issue with your company/process.

ever wondered why these large companies end up running things on random domains?

this is why
