New documents reveal that slides discussing surveillance of Google and Yahoo networks include references to Microsoft's Hotmail and instant messaging service, according to the Post.

Sources told the Post that Microsoft officials will meet this week to discuss the new encryption efforts.

When asked about Microsoft, the NSA told the Post that it only targets foreign individuals and does not conduct sweeping surveillance.

"NSA's focus is on targeting the communications of valid foreign intelligence targets, not on collecting and exploiting a class of communications or services that would sweep up communications that are not of bona fide foreign intelligence interest to the U.S. government," a spokesperson wrote in an email.
