How long this takes depends on your Internet connection and how many versions of Internet Explorer you chose to install.

This has been tested and confirmed to work with modern versions of all Mac system software, including OS X 10.10 Yosemite, OS X 10.9 Mavericks, 10.8 Mountain Lion, OS X 10.7 Lion, and Mac OS X 10.6 Snow Leopard. Notes: The administrator password for all IE virtual machines is “Password1” without quotation marks. This is accomplished using Oracle’s freely available VirtualBox software and combining Microsoft’s free Internet Explorer testing of virtual machines with the trick of converting these free IE vms to run flawlessly on OS X (or technically Linux), and everything is handled automatically method. We’ll show you how to install Internet Explorer 7, 8, 9, 10, and 11 on a virtual machine running Windows in Mac OS X – free. Run Internet Explorer 7, 8, 10, and 11 on Mac OS X the easy and free way Alternatively, there are emulators that can create a virtual machine on your M1 mac that emulates an entire Intel machine.

Things to look at: does windows for ARM have a copy of IE, and if it does: is it good enough for your needs? - if so: you could try Parallels + Windows for ARM technology preview (but you cannot buy a license for that windows at this time - legal at your employer might object). This is not so easy on an M1 than it was on an Intel based mac. Get a virtual machine on your M1 mac to run windows and IE in it in a virtual machine. Get a remote desktop to a windows machine that has the right version of IE for your needs. You could try 2 avenues, neither is super easy. Even Microsoft eventually saw the mistake and switched to Edge. Some companies drank too much of the Microsoft cool-aid in the days when IE was dominating the browser wars and built stuff that only IE will ever support. And it's even more dead on mac, let alone on M1 based ones.
