Microsoft adds ransomware protection to OneDrive, Outlook.com

"Today, we're reporting new propelled insurance abilities coming to Office 365 Home and Office 365 Personal endorsers of assistance additionally shield people and families from online dangers", Kirk Koenigsbauer, Corporate Vice President, Office 365 Client Applications-Microsoft, wrote in a blog entry late on Thursday.

Explaining the files restore feature, Microsoft added: "Files Restore allows you to restore your entire OneDrive to a previous point in time within the last 30 days". Users also can use this feature to recover from an accidental mass delete, file corruption, ransomware, or another catastrophic event, officials noted. Thankfully, Microsoft has now made that feature available to any OneDrive subscriber (we're chasing Microsoft to see if this feature will come to free OneDrive accounts as well). They pinpoint the time and date of the attack and restore OneDrive and Office 365 files to their state prior to the attack.

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

In January, Microsoft announced that OneDrive for Business Files Restore would be coming to Office 365 Commercial users.


Recipients receive a link to a trusted Office 365 webpage where they can choose to receive a one-time passcode or re-authenticate with a trusted provider before viewing the email.

The password requirement has now also been extended, with an additional security option for links shared from OneDrive. Outlook.com email recipients who view the encrypted email in Outlook.com, the Outlook for iOS and Android app, or the Windows Mail app can read and reply just like they can with any other email-no extra steps needed.

Microsoft's bringing a key Outlook.com security feature to its Office apps later this year as well.

The new email encryption feature in Outlook.com offers an added layer of protection and ensures end-to-end encryption of users' email. And lastly, OneDrive is getting the ability to password-protect shared links, which means you will be able to now give users with a password to access your files or folders within OneDrive. Outlook.com already has advanced link checking and attachment scanning built in; the addition of link scanning to Word, Excel and PowerPoint for Office 365 consumer subscribers will be rolling out in the second half of 2018. Once this feature is enabled, when you click links in Word, Excel, and PowerPoint, links will be checked in real-time to determine if the destination website is likely to download malware or if it's related to a phishing scam.
