Microsoft 365 provides a strong foundation, but the safest settings are not always enabled automatically—especially in tenants that have grown over time. A focused configuration review can close common gaps without disrupting how employees work.
Five useful checks
- Multifactor authentication is enforced for all users, including administrators.
- External email forwarding is restricted and monitored.
- Legacy sign-in protocols are disabled unless there is a documented exception.
- Mailbox auditing and alerting are enabled and reviewed.
- Sharing policies match the organization’s actual need to collaborate outside the company.
Configuration is not a one-time project
Licensing, staff roles, threats, and Microsoft features change. A setting that was reasonable two years ago may no longer fit the business today. Reviewing the environment on a regular schedule helps prevent old exceptions from becoming permanent risk.
