**VERDICT: FAKE**

> **⚠️ URGENT FBI ALERT: Outlook & OneDrive Users at Risk!** 🚨
>
> The FBI has reportedly issued an emergency warning for all Microsoft Outlook and OneDrive users. According to the viral alert, hackers have found a way to clone your entire inbox and cloud files using a "zero-click exploit" that activates simply by opening the Microsoft 365 mobile app. The post urges users to immediately delete the app, change all passwords, and freeze their credit. It claims that encrypted, password-protected USB drives are the "only safe alternative" for storing documents moving forward.
**Why it’s fake:**
The FBI has *not* issued any such alert as of the current date. The claim about a novel "zero-click exploit" cloning entire inboxes via the mobile app is not supported by any official advisory from CISA, Microsoft, or the FBI. While phishing campaigns targeting Microsoft 365 are real and ongoing, this specific description of a "clone your entire OneDrive" attack does not match any known vulnerability. The recommendation to freeze credit and abandon cloud storage entirely is an extreme overreaction that signals a scare tactic, not a genuine security bulletin. Always verify alerts on official domains like **FBI.gov/IC3** or **Microsoft Security Response Center** before taking action.
