Knowledge Base & Operational DocumentationHow to Review Access to Shared Administrative Mailboxes
11/10/2026
Shared mailboxes can contain sensitive messages while access remains after a user changes role or leaves.
Checks to make
List direct and group-based access, delegation, forwarding, and recovery options. Confirm each grant has an owner and business need, review audit coverage, and remove stale access through the approved process.
When to get help
Cybersecurity advisory can review mailbox access and delegated permissions. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
