IME, the IE11 users have all been able to use another browser.
Then your company must not have any customers in security-conscious industries like healthcare.
Any well-run IT department doesn't just allow the company's employees to install and run any old browser they want because a web site told them to do so.
I am forced to support IE11 because a very large number of doctors, hospitals, and other healthcare providers use it. These people cannot simply "fire up chrome/Firefox/edge."
It's not very security-conscious of them to continue using IE11. These healthcare companies are being incredibly irresponsible by continuing to use an insecure and outdated browser; even going against Microsoft's own recommendation in doing so, as I understand it. By supporting IE11 your company is helping to enable the healthcare industry to continue using insecure software.
A well-run IT department should be able to provide its users with a modern and secure browser. Why does your definition of a well-run IT department include the requirement that software installations should be restricted, but not a requirement to avoid using insecure and outdated software?
I believe one can make a compelling case that the continued use of IE11 within the healthcare industry is unethical, as it provides a known attack vector by which people's data can potentially be stolen. Stop giving them a pass on this.
Yes, I'd have to ask those users to log in with their iPhone :)
Seriously though, the IT-only-allowing-IE11 hasn't been a sales or support blocker in the last couple years, as it has been for me in previous companies 5+ years ago, but YMMV
Every site like Stack Overflow or Google Docs that doesn't work with IE11 helps convince decision makers that maybe their IT department should actually get with the times
