My first email was Hotmail n 1995. Microsoft bought it a long while ago and made it a domain under their Outlook. Now they are preventing any other app from downloading folders or emails from it, so '''I need to keep the emails that successfully made it into Tbird folders BUT avoid Tbird from ''ever'' trying to connect with it ever again''' (it hangs the whole app). They want users to be fully captured by their apps, and thereby to receive all fees and subscriptions, but they are careless and manipulative — arbitrarily blocking paid subscriptions, replacing preferred news source with their own, etc. — so I'm not going to sign up for anything not absolutely necessary (i.e. — for now — Word). I am seeking guidance as to how to create just that situation. I did it 7..5 years ago when I retired, since the college where I taught immediately closed my email account there, but I can not figure out how to do it now. Thanks in advance.
