Full access rights are the highest level of access to a mailbox or a shared folder, so they should be delegated only to Exchange administrators or trusted employees. Many organizations have policies that permit admins to access other users’ mailboxes for support reasons and in-house HR or legal investigations, and to delete a mailbox when the user leaves the organization; otherwise, they should not be using those elevated permissions. With access auditing enabled, you can log mailbox access by users who are not mailbox owners to ensure there’s no abuse of privileges in your Microsoft Exchange Server environment, thereby hardening the security and privacy of your email information.

Enabling Exchange mailbox auditing with built-in tools

In addition to mailbox auditing, you need efficient permissions management, so you can ensure that only valid users or admins have the ability to access other users’ mailboxes and view email messages in them. When it comes to auditing Exchange mailbox access, you can use the built-in tools, but you’ll need to write PowerShell scripts to run commands enabling mailbox audit in the Exchange Management Shell. Be prepared to spend some time on this task, because you’ll also have to write scripts to set mailbox audit logging on multiple mailboxes, retrieve audit log entries, and export audit log entries into Excel format — and then you’ll have to spend even more of your valuable time to turn that raw data into useful reports. Are you ready to dust off your PowerShell skills and spend your lunch breaks in the office? On top of that, keeping audit logs requires large amounts of disk space, and native tools simply can’t help you out with this. So is there a way to enable efficient mailbox auditing that you can rely to keep your mailbox data secure?
