We are excited to announce the addition of ransomware detection and recovery, an expanded Personal Vault, password protected and expiring sharing links, and offline files and folders to Microsoft 365 Basic.

With additional security features from OneDrive, Microsoft 365 Basic subscribers will get additional peace of mind for their files and photos, at the same low price.

Let’s take a look at the newly added features and some helpful tips to get you started.

Ransomware detection and recovery

How it helps: By storing your important files and photos in OneDrive, you're not just backing them up in the cloud; OneDrive vigilantly monitors them for signs of ransomware.

How it works: Our system monitors your account for signs of ransomware activity. This includes unusual file modifications, encryption actions, and other indicators of malicious intent.

OneDrive alerts you to ransomware on your device and via email.


When Microsoft 365 detects a ransomware attack, you’ll receive a notification on your device and an email from Microsoft, alerting you to the potential threat. We guide you through the process of assessing the extent of the issue, deleting suspicious files and then help you identify a safe point in time for restoration.

OneDrive will update you when the restoration completes.


While there's a possibility of losing some data between the time of infection and detection, this measure mitigates the loss, safeguarding your most crucial files and memories. Check out this article for more detailed information on recovering your OneDrive.

Personal Vault

How it helps: Personal Vault in OneDrive provides an extra layer of security with Two-Factor Authentication (2FA), helping to ensure that only you can access your critical files. This feature is invaluable for important documents, such as passports, tax records, and financial documents, as well as any photos or digital keepsakes you hold dear. Microsoft 365 Basic subscribers previously could only store 3 files in their Personal Vault. That restriction has now been removed, and subscribers can put as many files as they want in Personal Vault up to their 100GB storage limit.

How it works: Activating your Personal Vault is straightforward and requires just a few steps:

1. Start by Logging In: Navigate to and sign in with your Microsoft credentials.

2. Enable Personal Vault: Head over to Settings and find the Personal Vault option. Click "Enable" to begin the setup.

3. Choose Two-Factor Authentication (2FA): For enhanced security, enabling your Personal Vault requires 2FA. You can opt to use a secondary email or, for optimal security, use the Microsoft Authenticator app available on both iOS and Android platforms.

4. Enter Your PIN: Upon setup, you'll receive a PIN through your chosen 2FA method. Enter this PIN to activate your Personal Vault.

Every time you access your Personal Vault, you'll be prompted to authenticate via your selected 2FA method, ensuring that only you can view and edit your most sensitive files.

Personal Vault: Tips

Regularly Review Your Vault: Periodically assess the files in your Vault to ensure that everything stored there is still relevant and requires the extra layer of security.

Securely Close Your Vault: While your Personal Vault will close automatically after 20 min on inactivity, it’s a smart move to just close Personal Vault after you’re done. This simple habit ensures that your sensitive files remain locked away, even if you forget to close your browser.

Offline Access: Tips

Plan Ahead: Before traveling or entering areas with poor connectivity, preemptively select important documents for offline access.

Storage Considerations: The number and size of files you can store offline are limited by your device's available storage and the Microsoft Basic 100GB storage limit. Keep an eye on your device’s capacity to ensure optimal performance.

Data Management and Usage: Be mindful of your data plan when enabling offline access for large files or folders, especially if relying on cellular data. Syncing large files or numerous folders can consume significant amounts of your data plan. To avoid unexpected data usage, consider syncing over Wi-Fi or adjusting your sync settings.

Manage Storage: Regularly review and remove offline files you no longer need to free up storage on your mobile device.
