Project Honolulu is Microsoft’s brand new, still under development, browser based admin tool. It can’t use Internet Explorer – it only supports Microsoft Edge or Google Chrome.
Windows Server 2016 (and all earlier versions of Windows Server) only has Internet Explorer. MS Edge isn’t available on Windows servers.
If you use a jump off server for your administrators like many organisations do, you can’t use the web browser on that server to access Honolulu unless you install Chrome.
So we have a new Microsoft admin tool that doesn’t support Microsoft’s browser.
You can’t make this stuff up.
