Microsoft on Tuesday said it is scrambling Outlook email messages in transit to thwart spying by governments or others. Toughened encryption at Outlook and Microsoft OneDrive online cloud data storage service came less than a month after the technology titan got low marks in a Google ranking of such defenses against online snooping. We are in the midst of a comprehensive engineering effort to strengthen encryption across our networks and services, Microsoft vice president of trustworthy computing security Matt Thomlinson said in a blog post. This effort also helps us reinforce that governments use appropriate legal processes, not technical brute force, if they want access to that data.
