Why Microsoft’s
Built-In Tools Aren’t Enough.
Microsoft 365 does not include a traditional backup solution. Instead, Microsoft provides native retention and recovery features such as recycle bins, version history, and retention policies. These tools are designed to support availability, but they do not safeguard you against disaster, ransomware, insider threats or compliance audits. Under Microsoft’s Terms and Conditions their Shared Responsibility Model states that customers are responsible for protecting their own Microsoft 365 data. This means your essential business communication and collaboration are vulnerable, unless you have a dedicated Microsoft 365 backup solution in place.
Microsoft's Limited Retention Windows
Deleted emails and files are only recoverable for a short time. Once retention periods expire, data is permanently lost.
Retention Is Not Backup
Microsoft's retention policies focus on compliance, not recovery. Restoring specific emails, files, or folders can be slow, complex, or impossible.
Same Security Boundary
Microsoft 365 data and retention settings live inside the same tenant. If an admin account is compromised, attackers can delete data and disable protections, leaving no clean recovery copy.
No Protection Against All Threats
Native tools do not reliably protect against ransomware, insider threats, mass deletion, or sync errors discovered weeks or months later.
