I created a new task and accidentally clicked the "monitor sub directories". In the sub directories there are thousands of files that meet the conditions for the watcher to send out an email. I've edited the watcher so that it should not send out emails for files in sub directories but it seems that the watcher has already scanned the sub directories and has an email for all of these files in a queue. Can someone please help me out by letting me know how to clear out this queue of emails?
