Identify and Handle Potential Phishing Emails

Check for common red flags of phishing and safely report the suspicious email without clicking any embedded links.

Phishing scams often masquerade as official policy updates to create a false sense of urgency. Even if an email looks legitimate at a glance, scammers can easily spoof logos and formatting.

1
Inspect the Sender Address

Hover over or tap the sender's name to reveal the actual email address. Look for misspellings or domains that do not end in official Microsoft domains like @microsoft.com or @accountprotection.microsoft.com.

2
Check for Generic Greetings

Official Microsoft communications regarding your account will typically address you by the name associated with your account, rather than a generic 'Dear Customer' or 'Dear User'.

3
Look for Warning Banners

Pay attention to built-in Outlook warnings, such as 'This email was sent from an unmonitored mailbox' or alerts that the sender failed fraud detection checks.

4
Report the Suspicious Email

Select the message in Outlook, navigate to the Home tab on the ribbon, and click 'Report Message' > 'Phishing' to send the data to Microsoft and delete the email from your inbox.

Frequently Asked Questions

Do the Microsoft Services Agreement terms of use apply if I don't pay for a subscription?

Yes. The Microsoft Services Agreement covers many free products and services, including Outlook.com, OneDrive, and Skype. You may receive legitimate update emails even if you do not have a paid Microsoft 365 subscription.

Why does Outlook show a warning that an email was sent from an unmonitored mailbox?

This banner indicates that the sender's email address is set up only to send messages and cannot receive replies (like a 'no-reply' address). While legitimate companies use these, scammers often mimic them to prevent users from questioning the email's origins.

What is the safest way to review Microsoft policy changes?

The safest method is to ignore the links in the notification email altogether. Open your browser, go to a search engine, and type 'Microsoft Services Agreement'. Click on the official Microsoft.com link to read the terms securely.
