Email client for Windows 10 that will read Apple Mail flags

I have a Windows 10 laptop which is using Microsoft Mail, whose search function doesn't work very well and I'm frequently unable to find the emails I am looking for except by finding them on my Mac Mini and forwarding them to myself. I want to find a new email client for the Windows Laptop and I'm looking for recommendations that will work well for someone used to Apple's Mail client, particularly if it could read the Apple Mail Flags. Thank you for your consideration.

There was a similar post but it was in 2006 and didn't mention Apple Mail flags.
