Connector Overview
Monitoring Microsoft Exchange On-Premises is based on standard Microsoft Exchange monitoring capabilities. Access to Exchange On-Premises is based on Remote Power Shell capabilities.
Audit types include:
Mailbox Access Audit
Administrators who access other users’ mailboxes
Users who access other users’ mailboxes as delegates
Owners who access their own mailbox
Administrator Audit PowerShell Cmdlets
Every Set-* PowerShell is audited
It is not recommended to enable Owner auditing on all mailboxes, due to Exchange overload and DB size.
