Microsoft updates end-to-end encryption for Teams calls

Microsoft started testing end-to-end encryption on Teams calls two months ago. Microsoft notes that IT administrators will have the option to enable and control E2EE in their organization when it is updated. Microsoft is prioritizing E2EE updates for corporate customers in the US and Europe in critical industries such as aerospace, manufacturing, telecommunications, and professional services.

IT administrators will have the power to configure policies and enable E2EE for certain users or a certain group of users. Then, when you want to use it, users will have to manually enable E2EE in Teams' settings. If necessary, administrators can immediately disable E2EE for any user in the network they manage.

Another note that you need to pay attention to is that when E2EE is turned on, some Teams features will be disabled. Below is specific list:

1. Record
2. Translate and provide subtitles online
3. Call transfer
4. Call Park (put on hold)
5. Call Merge (merge calls)
6. Call Companion and transfer to another device
7. Add people to turn 1:1 calls into group calls

If these features are important to you then you need to go into Teams settings and disable E2EE so they can work again.

Microsoft has not yet mentioned anything about updating E2EE for individual users.
