Office 365 Security Audit – Users, Mailboxes and One Drive

Whether it is on-premises or the cloud, the most important question of  who has access to what has to be always answered by Admins and IT managers, especially during Compliance and Security Audit. When it comes to Office 365, this question is even more significant as end users share their mailboxes and data for various business reasons. Most of data security breaches happen due to indiscriminate accesses given to users and failing to remove these accesses when users leave or move to a different department in the organization. Accesses may happen due to group memberships, sharing of mailboxes and Public Folders, sharing of One Drive content and so on. The permission levels, such as Full Access to a mailbox, determine the vulnerability to a security breach. Any Office 365 environment needs to be audited for security to determine who has access to what and whether such accesses have been authorized or not.
