Currently, Microsoft Teams does not support end-to-end encryption for meetings. Data is encrypted in transit and at rest, and this allows authorized services to decrypt content for data retention record purposes. Microsoft currently uses Share. Point encryption to secure at-rest files and One. Note encryption for notes stored in Microsoft Teams.
While Microsoft Teams already encrypts data at rest and in transit, it allows administrators to configure automatic recording and transcription of voice calls. Due to this, Microsoft Teams calls are not suitable for sharing very sensitive information that should remain private between two individuals.

Sign in to the Teams admin center and navigate to Other settings > Enhanced encryption policies. Name the new policy, then for End-to-end call encryption, choose users can turn it on, and then choose Save.
