End to end encryption with Microsoft Teams?

I am aware that Microsoft Teams has data encryption at rest and in transit. But is there a way to use E2EE? If not is metadata at least encrypted? Thanks - Hayden

    Jleebiker The mobile client supports App Protection Policies from InTune that would ensure that it's content is encrypted and users are authenticated on the end point device.

     

    E2EE means something different. It means that the messages are encrypted on the senders device and can only be decrypted on the recipients device. All of the infrastructure in the middle is irrelevant as it can not decrypt the content at all. This is not how Teams works, while every stage of the journey is encrypted the service in the middle can decrypt content if it needs, for example to store data within the retention records or if you add a new person to the conversation. E2EE is only really relevant in apps which don't have any central services.
