Microsoft is expected to offer end-to-end encryption for the popular Teams app. This means that our conversations will not be stored on Microsoft’s servers, and the data will only be encrypted and decrypted on the interlocutors’ devices, so we will be able to count on the utmost privacy. A beta version of this functionality will be commercially available in the first half of 2021.
It should be noted at the outset that end-to-end encryption will only be available for two-person calls that have not been previously scheduled. Meetings of three or more people will continue to be encrypted in real time (“on the go”) and on breaks, so data is transferred to Microsoft Azure servers.
When might end-to-end encryption introduced in Microsoft Teams be useful? First of all, for confidential conversations using sensitive company data, or for technical support, where the network administrator provides login details to the person corresponding to the employee, or in other cases where such support is required.
Microsoft plans to implement end-to-end encryption for scheduled individual and group meetings at a later date.
Initial release of fully encrypted conversations between two people will be available in Microsoft Teams in the second quarter of 2021 at the latest.
