One-to-one Microsoft Teams calls finally have the security of end-to-end encryption
Microsoft is improving the security of one-on-one Teams chats by adding end-to-end encryption. After a couple of months of testing the feature as part of a public preview the company says that the optional security boost is now generally available.
In order for calls to be protected, both parties need to have end-to-end encryption enabled. And if you're wondering why you might want to have E2EE disabled in Microsoft Teams, it's because having the security feature enabled means that some other call features do not work.
