In window Server Alert Log there are many logs that weren't deleted by Server Log Cleanup task.

Logs weren't deleted because they hadn't been marked as Checked. When user manually marks the log as Checked, the Cleanup task delete this log, but in the environment there are more than 12 millon of logs, so there is no possibility to mark manually all of them. So, is there any possibility to delete these logs and verify if there is any possibility to delete logs automatically without marking them manually as Checked?
