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

Me also. I have changed my password, and added two step security. The messages are coming into my in box and into my back up email When I informed microsoft that THIS IS NOT ME I get a message saying site unavailable. All the activity is coming from the US Redmond Washington with similar but not exactly the same VPN.

Olá. Eu moro no Brasil e não estou fora do meu país acessando a conta.

Hackers invadiram meu computador e corromperam o Windows do meu notebook e não estou conseguindo atualização.

Podem ajudar-me?

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.

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

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