When an employee leaves, their Microsoft 365 access should be blocked promptly and the business should secure, transfer and retain any important company data before the account is removed.
Active sessions may also need to be revoked, while email, OneDrive files, shared content and the Microsoft 365 licence should all be reviewed. The exact process depends on how your environment is configured.
See Microsoft’s guidance for removing a former employee, or ask Kazzoo about business IT support.
