What service does Microsoft manage all cryptographic keys used for encryption by default?

Microsoft manages all cryptographic keys used for encryption by default across various services, including Exchange Online, SharePoint Online, and OneDrive for Business. This centralized management of cryptographic keys is essential for ensuring strong security protocols and compliance with regulatory requirements related to data protection.

By managing keys for these services, Microsoft provides a streamlined approach to encryption that simplifies the user experience while maintaining high security standards. Users do not need to worry about the complexities of key management as Microsoft takes care of the generation, storage, and handling of these keys.

This practice builds trust and assurance for organizations utilizing these services, as they are protected by a robust encryption framework managed by Microsoft. As a result, the correct choice encompasses all the mentioned services, as they all rely on Microsoft for cryptographic key management in a default configuration.
