🧭 1. What Is a Suspicious Sign-In Notification?
Microsoft sends a security alert if it detects a sign-in from:
- A new location (country or region)
- A new device or browser
- An unusual IP address
These alerts are meant to help protect your account from unauthorized access.
However, these alerts can also be triggered by legitimate activity—like logging in from a hotel or using a VPN.
🕵️♂️ 2. Is the Email Real or a Phishing Scam?
Scammers often impersonate Microsoft to trick you. Here’s how to tell the difference:
| Check Point | Legitimate Email | Phishing Email |
|---|---|---|
| Sender Address | account-security-noreply@account.microsoft.com | Strange domains (e.g., @m1crosoft.com, or unusual character combinations) |
| Link URL | Starts with https://account.microsoft.com/ | Contains suspicious or misspelled domains |
| Language | Neutral and informative tone | Urgent and threatening words or phrases like “immediate action required” |
💡 Important Tip: Don’t click any links in the email. Instead, go directly to https://account.microsoft.com in your browser.
🔍 3. How to Check Your Microsoft Account Sign-In Activity
If you’re unsure whether someone else has accessed your account, review your official Sign-in Activity log.
Steps:
- Go to: https://account.microsoft.com and log in.
- Navigate to Security > Sign-in activity.
- Review the location, device, and IP address.
- If anything looks suspicious, click “This wasn’t me.” to report it.”
📍 You can even view a map to check the sign-in location. If it’s a country you’ve never visited, take action immediately.
🚨 4. What to Do If It Was Unauthorized Access

1. Immediately Change Your Password
