The Exchange Logga Filter is designed as a blacklist filter. Blacklist means here: The Exchange Logga records to the maximum extent. You determine which events are not recorded (discarded).
The filter criteria work additively. An event is rejected if criterion 1 or criterion 2 or criterion 3 applies, or several criteria simultaneously.
The filter criteria are not correlated with each other. The events are evaluated by the Exchange Logga one after the other according to the criteria. In the case of a hit, the event is immediately rejected and no longer checked, regardless of whether another criterion has already been evaluated or not.
If user A is configured as an "action author" filter, all changes made by him in Exchange will be discarded, even if the actions or roles he has performed are not configured as a filter.
