I have a rule that moves emails from my Inbox to a specific folder. These emails are alerts from a SharePoint list that something has changed.

When a new alert comes in...I would like to be able to search through the folder and delete any previous emails that match the subject line. The subject is always the same "Project List Change - xxxxx".

Is this possible? I see the "run a script" and "perform a custom action" steps, but not sure how to use those.

Thanks in advance
