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

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.

- I am also interested in this issue. MS announced a partnership with Signal to use their tech to do E2E encryption for Skype for Biz, what is being done for Teams?
Jleebiker All Teams data is encrypted "in transit and at rest" see https://docs.microsoft.com/en-us/microsoftteams/security-compliance-overview.
I'm not really sure what E2EE would mean in a Teams context, it's typically for consumer type apps where the data is only decrypted on the end client devices. Teams can't be this, the data resides in Office 365 and is subject to retention and ediscovery.
StevenC365 Webex teams and Symphony both have end to end encryption which are not cunsomer types apps. Also for banking clients like us E2EE is more and more important . We moved from SFB to Webex teams our 100 K users and we also use symphony.
I don't see why MS teams cannot offer E2EE encryption , I am pretty sure even Zoom meetings and Chat along with Webex meetings offers E2EE now.
