Why Has My Google Mail Been Disabled?

Using POP Or IMAP

Mail software programs such as Outlook and Apple Mail use protocols called POP and IMAP to download messages from Internet email accounts. If you download, receive or delete large amounts of mail in a short period of time with one of these programs, this can appear to Google like someone is using your account for illicit activity like sending spam. You know that this is the case if you receive the error message 'Lockdown in Sector 4.' Wait for about 24 hours, and you should be able to access your account again.

Multiple Undeliverable Messages

If you are sending many messages that bounce back to you, this can appear to Google like someone is trying to send spam from your account. Google may reinstate your account after reviewing your activity, or it may be permanently disabled if you are violating Gmail Terms of Use.

Suspicious Programs, Extensions And Behavior

File-sharing or file-storing software, third party software and browser extensions that automatically log in to your Gmail account can look suspicious because it may appear like an automated program is using your account for illicit purposes. You might also accidentally disable your account for the same reason if you have Gmail open in multiple windows at once. If you are not engaging in suspicious activity, account access should be restored within 24 hours.

Browser Problems

It is possible that you are not experiences problems with Gmail itself but your browser is unable to access your account. If it repeatedly reloads when you try to access your account, the problem is with the browser. To address this problem, install any updates from your browser's manufacturer, and clear your cache and cookies. If you are not sure how to do this, refer to 'Help' or 'Support' from your browser. If all else fails, try accessing your account with a different browser.

Account Compromised

It is possible that someone is using your account without your permission to perform illicit activities. If this is the case, Google can reinstate your access to your account by helping you reset your password.

Policy Violation

Google may permanently disable your account if you did, in fact, violate Gmail Terms of Use. If you did not violate the Terms of Use and believe that your account was disabled by mistake, contact Google for assistance.
