Parameter Required Type Description




The Identity parameter specifies the name of the event logging category to display.




The Level parameter specifies the log level for a specified server running Microsoft Exchange.




The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.
