If the account is still accessible, it is not currently suspended in a way that blocks sign-in.
For Microsoft account security alerts, the reliable way to verify the status is to check the account directly instead of trusting the email alone:
- Go to the Security basics page.
- Select Review activity and inspect the Recent activity page for unusual sign-in attempts.
- If an activity is not recognized, select This wasn't me for items in Unusual activity, or Secure your account for items in Recent activity.
- If there is any chance someone accessed the account, return to Security basics and select Change password.
A legitimate unusual sign-in email from Microsoft is from ******@accountprotection.microsoft.com. If the message came from a different sender, treat it as suspicious.
Microsoft can temporarily block sign-in when unusual activity is detected, but when that happens the sign-in flow normally instructs where to receive a security code to unlock the account. Since normal access is still working, the email alone does not confirm that a suspension is active.
