Re: End-to-end encryption for 1:1 Microsoft Teams calls 

Dear colleagues,

This is to inform you that we will be enabling “End-to-end call encryption” (E2EE) for Microsoft Teams unscheduled 1:1 calls. Users will have the ability to toggle this feature on or off as needed. 

E2EE ensures that your call content is encrypted before it’s sent and decrypted only by the intended recipient. This means only the two endpoints can access the call data, and no other party, including Microsoft, can decrypt the conversation. 

For detailed instructions on how to enable or disable this feature and to understand how it may impact certain advanced Teams call functionalities, please refer to this knowledge base article. 

If you have any questions or concerns, please submit a ticket to the Enterprise Service Centre at (https://uoft.me/m365help). 

Kind regards,
