Configure Infrastructure for Monitoring Exchange Online
Exchange Online audit configuration will depend on the monitoring scenario:
If you do not plan to monitor non-owner mailbox access, consider that Netwrix Auditor will set up the auditing of the target Exchange Online automatically. Then it will check these settings at each data collection and adjust them if necessary.
To audit non-owner mailbox access, additional configuration steps are required; for that, you can choose either automated or manual procedure.
