Microsoft account unusual sign-in activity email, -----> Is this phishing?

Can anyone explain why I still receive mail for the supposedly blocked account?

Goodness, I am getting these emails multiple times a day, to both my registered email and the back up recovery email address. I independently logged into my account and changed the password after the first few alerts I received, but I'm still getting them, even today. It's the last week or so it's continually doing it. Pleased to see it's not just me!

It's getting annoying now. I don't think this is some hacker - I think it's Microsoft's problem.

Same here except I use AT&T. I'm getting those same crazy emails.

I don't believe that they are phishing emails...I think they are from Microsoft. They all say they have detected "unusual" login activity. I login with the same devices on the same network everyday. I'm on a Mac computer with the latest OS and an iPhone with the latest iOS and an iPad with the latest iPadOS. I'm on Comcast internet wi-fi. I don't know what the variable is but nothing changes. But Microsoft's AI detects something and sends the notifications. There must be some error in the AI algorithm that detects the sign in. It sounds as if many, many people are being flagged with suspicious login activity.
