Outlook Windows PC email account problem

Recently, I have no longer been able to use my free email account on the Win 11 "mail" app.
I would like to point out that it worked well until recently, that the mail app identifies my other messaging services (hotmail).
So I tried to delete my free account on the app, to re-create it, and it doesn't work, whether in simple version (just asking for my account password) or "complete, by trying via pop or imap.
