Hotmail not in Thunderbird anymore. It is configured correctly. The 2 step verification process is OFF. Tried an alias, tried a new hotmail account. ZIP ZLITCH. Hotmail is my mail account and this has gotten insane. It logs in - goes to 'checking for new message' and then just hangs. No messages are pulled in. And then just disappears - no error - no sound - nothing. NO MESSAGES. I can send out okay Running Thunderbird 45.5.1 on Windows 10.

I HAVE FOLLOWED THE STEPS HERE https://support.mozilla.org/en-US/questions/1147439 no luck

Since the Hotmail address login issue should have been resolved by Microsoft, did you make sure POP access is still enabled in the web interface (also for the new account) in the first place, as described at the bottom of the Thunderbird and Hotmail article?

Also rule out your firewall/security software. Do you use any, which type/brand, and did/can you try disabling it?

It's working now. Thanks everyone. I had switched to an alias - outlook.com and it worked. [but I had both in TB the hotmail.com and the outlook.com] after seeing that Microsoft had addressed the issue - I switched the hotmail back to primary and deleted the outlook account from TB. Works great now. I am wondering if part of the problem was while my husband was at CC for over a month that I just had an insane amount of email back up in hotmail. Works now - happy for it as that is my main account and am now getting my messages.
