Strange messages in your Sent folder? Repeated login errors? Your BT Email account might have been compromised.
If we detect suspicious activity, we’ll block access immediately. You’ll see an error message in webmail or the BT Email app. If you use an email app like Outlook, you’ll notice repeated login failures.
What happens when your account is protected
When we block access, it’s to keep your account safe. Here’s what to do next:
- Run an antivirus scan on all devices you use for email - This removes any malware that could steal your login details. If you have BT Virus Protect, run it. On mobile, download antivirus software from your app store.
- Change your password at bt.com - Log in and select the Email link on the top bar. If you don’t have a BT ID, create one when prompted. Choose a strong password and update it on all devices.
- Follow the security checks below to make sure your account is fully secure
