You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Shell infrastructure permissions" section in the Exchange and Shell infrastructure permissions topic.


Parameter Required Type Description




The Identity parameter specifies the name of the event logging category for which you want to set the event logging level.




The Level parameter specifies the log level for the specific event logging category. The valid values are:

  • Lowest

  • Low

  • Medium

  • High

  • Expert




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.
