Secret documents obtained from the Guardian reveal that Microsoft was working closely with the NSA, providing them with access to emails on Outlook and Hotmail. Microsoft and the NSA developed a method whereby the NSA would be able to work around encrypted data on Outlook. In addition, nine months after Skype was acquired by Microsoft in 2011, the NSA tripled the quantity of Skype calls being monitored, which has approximately 663 million users.

Microsoft and other alleged companies involved in the Prism continue to deny their involvement in the program. Back in May 2013, Microsoft launched a campaign against Google titled ‘Scroogled’, which focused on Microsoft’s privacy centric app store which doesn’t share the personal information of people who download apps with the app developers unlike Google. However, with the exposure of these documents, Microsoft’s claim that ‘your privacy is our priority’ is discredited.
