Office 365 takes the responsibility of ensuring secure credentials and safeguards for mailbox data. It offers robust security features to detect and respond to threats promptly. In a cloud environment, there’s a shared responsibility model where Office 365 provides infrastructure, setup, availability, and durability, while accessibility is managed by users.
