In post #8; this caught my attention:
"On 3/24/2018 you requested that your security info be replaced."
I remember when I changed some of my security information, Microsoft locked me out of my own account for thirty days. Their explanation was that it was to discourage hackers and spammers. I was still able to access my email; however, I couldn't use or modify the account until the thirty days had elapsed.
If you requested that your security information be updated, then this explains a few things. If you didn't, then you should start taking steps to further investigate why you are receiving malicious requests.
