Configuring your Microsoft 365 tenant settings with security and usability in mind is essential for protecting your organization’s data and enhancing productivity. While the specific settings may vary depending on your organization’s needs, here are 15 important configuration changes you should consider:
1. Enable multi-factor authentication (MFA): Require users to provide an additional form of verification, such as a mobile app or text message code, when accessing Microsoft 365 services to protect against unauthorized access.
2. Set strong password policies: Enforce complex password requirements, including minimum length, complexity, and regular password changes, to prevent easy password guessing or brute-force attacks.
3. Implement Conditional Access policies: Define policies that allow or restrict access based on certain conditions, such as location, device compliance, or risk level, to ensure that only authorized and secure devices can access Microsoft 365 services.
