Hacked email account?

Hello,

Today, on my backup email, I received two emails 2 hours apart from the following address: account-security-noreply@accountprotection.microsoft.com

1. The first one was titled "Verify your email address" and stated:

Microsoft Account
Verify your email address
To complete the setup of your Microsoft account, we need to verify that this email address belongs to you.
Use the following code to verify your email address: [4-digit code]
If you did not request any code, you can ignore this email. Another user may have mistakenly entered your email address.
Thank you,
The Microsoft Account Team

2. The second one was titled "Verify your email address" and stated:

Microsoft Account
Verify your email address
To complete the setup of this Microsoft account, we need to verify that this email address belongs to you.
Verify [my backup email]
We may also invite you to provide the following security code: [4-digit code]
If you did not send this request, click here to cancel it.
Thank you,

Note that I had already received a similar email to the first one on January 27 and that this morning, upon starting Windows 10, I had this problem: https://www.malekal.com/windows-10-nous-ne-pouvons-pas-nous-connecter-a-votre-compte/ A simple restart allowed me to access my desktop.

Hence my questions:
- Is someone trying to hack my Outlook email? Did they discover my password, which would explain this confirmation request email from MS?
- Could the issue I had this morning when starting Windows be related?
- What should I do? Click the link in the second email to "cancel the request"? Change my password on this email account?

P.S.: mbam and antivirus found no anomalies on my laptop during the scans I performed this morning.

Thank you for your help,

mtl
