Give up on outlook already. Get a free gmail or hotmail account like everyone else is doing these days. You’ll get used to it in no time and you won’t miss outlook one bit.
There are a million windows clients.
Outlook.com will also allow you to use other email addresses.
Who is your email host?
When you say it “won’t accept” classic shell what happens when you try to install it?
I have win 10 and use live mail to read my other email account. I just no longer can read hotmail through Live.

Both work with Windows 10.
Windows 10 sucks. It forces you to set up an email account you may not want. It updates behind the scenes without your knowledge. It’s gadget heavy, so inefficient. There are too many problems to list. I despise it with a burning hatred of one thousand suns.
Oracle VirtualBox to run the older O/S (and important apps).
Win 10 comes with mail, from there you can add any pop3 or live account. I have Verizon, optimum and live running. For $400 or $100/year for 4 seats you can get office 360 (the $100 updates the $400 permanent 1 seat does not)
My suggestion is to move to an online platform and use mail. Mail has some quirks, but almost all email providers have a web based interface. So you use mail to see what is in your inbox and delete the crap and then the web for the things that are more important.

There should be no reason why your Windoze machine can’t use it.
You don’t have to have an e-mail. You can skip that and tell it you want to run it disconnected.
MAILBIRD isn’t quite up to Outlooks message rules, filters and such fancy features, but it’s still pretty nice. Make your own folders, etc.
Try it out.
Look for the nearly invisible 'Download now' link. Windows Essentials 2012 is a suite of programs on one installer package. I would uncheck all except Windows Live Mail 2007.
Of course I cannot be held responsible for your personal experience with this, but I have been pretty happy with my result. nb: YMMV

4th vote for Thunderbird.
I used Outlook Express until they took it away. Thunderbird was the next best thing. I can’t remember how I got all my e-mail over to it, but it’s probably an easy Google search away.
The other great thing about Thunderbird is that it will usually configure itself to get e-mail from big providers.
Try Opera Mail.

Dang. It wasn’t that long ago that Pegasus mail was always mentioned as an Outlook alternative.
I’m still on Win7 but have been pleased with Thunderbird for a long while - it recently added calendar appointments and tasks functionality and I’ve never had any trouble with it.
