Mailbox delegation is the granting of controlled access for one user or service to read, manage, or send from another mailbox under defined permissions. It matters because email often contains sensitive data and business authority that should not be shared informally.
What is Mailbox Delegation?
Organizations use mailbox delegation for assistants, shared operations teams, support workflows, and service accounts. Strong governance matters because delegated mailbox access can expose private data and create confusion around who actually performed an email action.
What Mailbox Delegation Commonly Supports
Common delegated rights include reading mail, managing folders, sending as another identity, or sending on behalf of another identity.
Mailbox Delegation vs. Credential Sharing
Mailbox delegation grants controlled shared access through formal permissions. Credential sharing gives others the original account secret and is far less safe.
