Email being sent to users who are no longer listed in the 'Notifications' tab of 'User (4354920)

In the GPOAdmin console, right-click on a domain, click 'User Preference', click the 'Notifications' tab.  If email is being sent to users that are not listed under 'Email Addresses', there may be some old entries in the Configuration container in Active Directory that need to be cleaned up.

1) Using ADSIEDIT, navigate to "CN=Users,CN=Wentworth,CN=QGPM,CN=Quest,CN=Services,CN=Configuration,DC=<DOMAIN>,DC=<COM>", find all old entries here and delete them (these are the list of users that emails are to be sent to). 

2) Find all old entries here and delete them (these are the list of users that emails are to be sent to). Check the properties of each entry and remove any entries that do not show a user / email address that is listed in the 'Notifications' tab of 'User Preferences'.

3) Refresh the GPOAdmin node of the Quest GPOAdmin console.

4) Test by checking out / checking in, etc. a GPO to make sure only the users listed in the 'Notifications' tab of 'User Preferences' get an email.
