Live.com login activity and a warning "Unusual activity detected"

Well, I have managed to mess up my live.com account so much that I cannot send or receive e-mail! That will probably solve my problem of unusual activities. That said, my account was messed up because I went to my microsoft.com account and added a new e-mail address to it. Then I deleted my live.com e-mail address from the microsoft.com account. Somehow, those accounts were linked and I cannot send or receive any mail at live.com address. Nor can I add live.com as a second e-mail address.

This is one massive convoluted, unnecessarily complex, and intertwined system. I am glad that none of these is my primary e-mail address. There is no need to make them this tightly connected. But, I will probably no longer receive unusual activity notices!

I’m having the same issue daily emails saying unusual activity. I’ve changed my passwords multiple times. And ironically the IP address of the unusual activity is traced back to Microsoft. How can I stop these it’s getting very annoying.

Thank you Yuhao Li for trying to help us. I ran a simple experiment, and here are the results:

1. On the computer where I have Thunderbird installed, I ran the account login activity
2. There was nothing unusual since yesterday
3. I started Thunderbird and checked all my mails
4. I refreshed the login activity page
5. And, there was a new entry, the login came from an IPv6 and no IPv4 that resembled the 13.101.XXXX sequence
6. I shut down Thunderbird and waited for 15 minutes and started it again, checking all mail accounts
7. Again, the IPv6 number was reported

That leads me to state that Thunderbird uses, when possible, IPv6 numbers or reports in that denomination. That said, I will not leave Thunderbird running on this computer when I switch to the other one.

Trying to change my e-mail address has already caused me a great deal of grief on Disqus and I cannot use my account to post comments anywhere. The problem is not directly caused by live.com but it certainly triggered the need to switch accounts. I am now stuck! And, not happy at all.

Thank you again for your efforts to find a solution to this matter.

Not all Thunderbird users are encountering this unusual activity issue, but it is worth a try.

As for "I would very much like to get guidance on how to switch out of this account", it is just like removing e-mail accounts from Outlook, you can refer to this post in Thunderbird forum: How to delete an email account in Thunderbird? | Thunderbird Support Forum | Mozilla Support

I do use Thunderbird on one computer for my live.com and hotmail.com accounts. While I get the unusual activity on my live.com account, the hotmail.com account is quiet as it can be, not a peep about any similar activity. I don't leave it on to keep checking mail and do not use that computer frequently as my other computer which runs Mailbird client.

I am not sure if it is indeed Thunderbird.

I would very much like to get guidance on how to switch out of this account. I tried at one place where I use it and got in a mess. Not the fault of live.com but the site. However, this is very annoying and I am not sure if it is affecting receiving mail.
