Very old Hotmail account

I receive email from that address/account and can send from the account too
[EDIT] to clarify, I do have to sign in to outlook.com first however using my outlook account.
and I'm not using a forwarding service such as 33mail, anonaddy, etc

Clicking on "Manage This Email" from the last post's previous screen shot brings me to this page :

I believe you have answered your own question: those two hotmail addresses are both associated with your MS account, and I would have thought you should just switch off the one you believe was compromised. In fact, unless you want to use the other one, turn it off also. You could do some tests from another (non MS account) to confirm which are still functioning, but it seems from what you have written that they both are.

If you click on the 'manage' link, you will see that MS refers to them as aliases.

Thanks @mngerhold,
From everything I've followed in this thread, I thought when a user opened a @HOTmail "account", it remained open until it was closed by the account owner.

those two hotmail addresses are both associated with your MS account

I'm not sure if that means these are aliases of my Outlook account. Do you mean the email service - Hotmail remained when the new Outlook migration occurred, but neither of them were ever MS accounts ?

well. I don't believe there's much a chance of this making sense.
My hotmail account was never closed
My two active Hotmail addresses confirmed by at least one member these are aliases of my Outlook account
Outlook.com and Hotmail.com accounts are separate Microsoft managed accounts
Nothing new learned about these hotmail addresses

I don't at this stage know what you are wanting to do: if those hotmail addresses work and you want to use them, carry on. If you want them gone, then simply switch them off from the 'manage' page.

Please accept my apologies, sir. I didn't intend to direct my frustration on anyone here at Tenforums.

Microsoft 's decision to move HoTMaiL user's to Outlook.com years ago impacted my HoTMail account.

The best that I can tell, after the HoTMaiL account became connected to the Outlook.com account and the move was successful, I lost the HoTMaiL account.

Unfortunately, there's nothing that can be done about that now.

Perhaps MS provided had an open window at one time for users to opt in to in order to prevent the action of the account from being closed.

Going back to old websites, you can either rename your account to outlook or create an alias.

Thank you all for your valued input.
One setting completely missed my eye.

The Sign-In Preferences change allowed me to select either of my Hotmail addresses to be used to sign-in. Its found by going to: Your Info > Contact Info > Manage This Email Address > Sign-In Preferences and then selecting (dot) the email address.

I found that both Hotmail addresses were not selected.

I made the sign-in preference selection for one of the Hotmail addresses. After logging out and signing back in with a Hotmail address I selected, I could successfully sign-in to Outlook.com

This is making more sense now but this is also embarrassing
I probably should consider an eye doctor appointment or something
