hate the new outlook that is replacing win mail. any alternative that is similar to win mail that is simple and fast to load?

Nothing is standardized beyond the plain email protocols from a thousand years ago. But your internet email contains plenty of proprietary stuff like calender and cloud storage.

Plenty of people were "celebriting" on January 1, 2025 that their windows mail app supposedly "survived" the December 31, 2024 deadline only to be caught a week or 2 later.

That reddit thread literally links to the workaround I found and I posted here. Batch script that repeatedly uninstalls new outlook and launches old mail.

Which points to the link to this post --- which on the last post stated it doesn't work anymore.

Premature Celebration.

Why would you have more than 10 email accounts? Do you mean your group or organization has more than 10? If just you...is creepy...are these for spam or phishing?

So once Gerard figures this out and creates the batch file...THEN he will be able to get his Microsoft domain emails (hotmail.com, live.com, MSN.com, OUTLOOK.com etc. ? ) Yes? No? Even though MS says you can't get to any of those without a program/mail handler that is compatible with the New Authorization system? (yeah, somewhere I have that MS email from nearly a year ago warning me of the deadline.)

Oh, maybe you mean he can use the old email to get his gmail, comcast, yahoo, whatever emails like I have done for years. MS has not at all been upfront and helpful in this transition. (MS user since 1990s...nothing has changed...if anything worse.)
