The $4.44M Question: What Happens When M365 Data Disappears?

The average data breach now costs $4.44M. For Microsoft 365 environments, the bigger issue is what happens in the hours after data disappears, not whether it was backed up.

M365 data loss shows up in three ways: a cyberattack exploiting compromised credentials, accidental deletion (34% of SaaS data loss), or an AI agent error that corrupts data silently, with no alert and no threat signature. Each requires a different recovery path, and legacy backup tools answer the wrong question. They confirm the data was saved. They do not tell you what to restore first, whether the backup is clean, or how to get the business back online.

The Day Without Your M365 Data lays out what legacy backup gets wrong, what a true recovery timeline looks like hour by hour, and how organizations like City National Bank of Florida and Verspieren kept 1,000+ and 1,200+ M365 users running through real incidents.
