The scam is known as the “Your Outlook Is Full” scam email, and it can compromise your account security and personal information. We will explain what this scam is, how it works, and what you can do if you have fallen victim to it.
What is the “Your Outlook Is Full” Scam Email?
The “Your Outlook Is Full” scam email is a fraudulent message that claims to be from Microsoft Outlook. The email informs the recipient that their Outlook storage has reached its maximum capacity, and that they need to verify their account details to avoid losing access to their emails and contacts. The email provides a link to a fake Outlook login page, where the user is asked to enter their username and password.
Here is how the “Your Outlook Is Full” scam email usually looks:

How does the “Your Outlook Is Full” Scam Email work?
The “Your Outlook Is Full” scam email is a classic example of phishing, which is a technique used by cybercriminals to trick people into revealing their sensitive information. The scammers use spoofed email addresses and logos to make their messages look legitimate and urgent. They also use fear tactics, such as threatening to delete the user’s data or suspend their account, to pressure them into clicking on the link and entering their credentials. Once the user does that, the scammers can access their Outlook account and use it for malicious purposes, such as sending spam, stealing contacts, or accessing other online accounts linked to the same email address.
What to do if you have fallen victim to the “Your Outlook Is Full” Scam Email?
If you have received the “Your Outlook Is Full” scam email and clicked on the link or entered your credentials, you should take immediate action to protect your account and your identity. Here are some steps you can take:
- Change your Outlook password as soon as possible. Use a strong and unique password that is different from your other online accounts.
- Enable two-factor authentication on your Outlook account. This adds an extra layer of security by requiring a code sent to your phone or email whenever you log in from a new device or location.
- Scan your computer for malware using Malwarebytes Free. Some phishing emails may contain malicious attachments or links that can infect your device with viruses or spyware.
- Report the scam email to Microsoft by forwarding it to reportphishing@office365.microsoft.com. This helps Microsoft identify and block phishing attempts in the future.
- Check your credit reports and bank statements for any suspicious activity. If you notice any unauthorized transactions or accounts opened in your name, contact your financial institution and report them as fraud.
