Three months after news first leaked, Microsoft officially announced today the launch of new anti-ransomware features for Office 365, the company's commercial subscription-based office tools suite.

The new feature is called File Restore and is a OneDrive feature that will allow users to go back in time and restore files to a previous state from the past 30 days.

OneDrive File Restore can be used for accidental mass deletes, file corruption, or any other catastrophic event, but Microsoft is marketing this feature as an anti-ransomware protection system for important files saved inside a OneDrive folder.

Unlucky users who managed to destroy their files or get infected with ransomware can find the new File Restore option in the OneDrive web dashboard.

Mobile alerts for when users get infected with ransomware

Additionally, Microsoft has also tweaked OneDrive's internal mechanisms to detect whenever an account's files might have been encrypted by ransomware.

In these cases, the Redmond company will send notifications to the user's smartphone, if the user has the OneDrive app installed.

This notification —pictured below— will alert users of ransomware infections as soon as they happen, and give users and companies the chance to revert affected files back to their previous state before production grinds to a halt.

But File Restore is not the only additions that Microsoft announced in the most recent batch of new Office 365 features. The OS maker has also deployed:

⦒ The ability to password-protected OneDrive-shared links
