Password Expiry Notification

Password Expiry Notification

Hey Guys, 
So I installed and configured the Free password expiry tool. I checked all the server settings with out network engineer and test the email connection in the server settings section. The test email sends fine, but when I run the task to email users with soon-to-expire passwords, they aren't receiving the emails. I have it set to only detect users in the OU associated with all users accounts, rather than the entire AD because I don't want managed and admin accounts to be included in the reports. Is there something I am missing in the configuration? Any help you can provide is much appreciated. Thanks!
