Beware of "Your Mailbox has Exceeded the Storage Limit" Phishing Scams

The email messages below, which claim that you have exceeded your email account storage limit or quota, are phishing scams. The email messages are fakes and were not sent by your email account administrator or provider. The fake email messages were instead created by cyber criminals to trick you clicking on the links in them that go to a phishing website that steals email account username and password.

Please continue reading below.


Once the cyber-criminals behind the scam receive your email account username and password, they will use it to hijack your email account, send spam and other malicious email messages to your friends, family, and other persons, in an attempt to trick them into stealing their account usernames and passwords.

Remember, your email account will never be closed, deactivated, shut down, suspended, deleted because you have exceeded your storage limit or quota. What will happen is: you will not be able to receive new email messages. New messages will return or bounce back to the sender, letting them know that your mailbox is full. Also, in some cases, you may not be able to send email messages.

Therefore, never respond to any email message like the ones below, which threatens to shutdown, delete or suspend your account, and asks you to click on a link or visit a website. Go directly to your email account and sign-in from there instead. After signing in, you will be notified if your mailbox is full or you have exceeded your storage limit.

    The best thing is they use 'loose' instead of lose and there instead of their.

    I noticed this a lot in various scams. One was to 'bank of amrica' which went to a scam site.
