In today’s digital world, email hacking incidents are unfortunately becoming more common. When your Office 365 email is hacked, it’s important to act swiftly to minimize the damage and secure your account. In this blog post, we will outline the steps you should take during this difficult situation.

Your Office 365 Email is Hacked

What to Do if Your Office 365 Email is Hacked

Change Your Password

The first step after suspecting a hack is to change your Office 365 email password immediately. Opt for a strong, unique password that includes a combination of uppercase and lowercase letters, numbers, and special characters. Avoid using easily guessed passwords or those commonly associated with you.

Enable Multi-Factor Authentication (MFA) in Office 365

Enhance the security of your Office 365 account by enabling multi-factor authentication (MFA). This added layer of protection requires a second form of verification, such as a code sent to your mobile device, in addition to your password. MFA helps prevent unauthorized access even if your password is compromised.

Check for Unauthorized Activity

Thoroughly review your email account for any signs of unauthorized activity. Look for strange emails, deleted messages, or changes to your account settings. Pay special attention to sent items and check for any automatic forwarding rules or unusual replies that may have been set up without your knowledge.

Update Recovery Information

Ensure that your account recovery information, such as alternate email addresses and phone numbers, is up to date. This will be helpful if you need to regain access to your account or recover your hacked email.

Scan Your Devices for Malware

Perform a comprehensive antivirus scan on all devices you use to access your Office 365 email. Malware could be the root cause of the hacking or could  lead to further compromises. Removing any malware from your devices is crucial for securing your email account.

Notify Your Contacts That You Have Been Hacked

Inform your contacts about the potential hack and advise them to be cautious of any suspicious emails or requests originating from your account. This helps prevent the spread of malicious content and keeps your contacts informed about the situation.

Report the Incident

Contact your organization’s IT department or Office 365 administrator to report the hacking incident. They can provide further guidance and support, as well as assist with additional security measures to protect your email and other systems.
