In the digital age, email has become a critical communication tool for businesses. However, with the increasing frequency of cyber attacks, it's essential to ensure robust email protection. Microsoft Office 365 offers a suite of powerful tools to secure your emails, but it's crucial to follow best practices to maximize security. Here are 15 best practices for Office 365 email protection:

MFA adds an extra layer of security by requiring additional verification, such as a code sent to your phone, beyond just a password.

Office 365 includes various security features like Exchange Online Protection (EOP) and Advanced Threat Protection (ATP). Ensure they are enabled and configured correctly.
