Can anyone tell me how to write a rule that will delete previous e-mails with
the same number in the subject? I receive e-mails with subjects similar to
the following: "XYZ Company Issue #5506384." I would like Outlook to only
keep the most recent version of the e-mail for that issue. The e-mails are
sent by various employees from the company and the subject may have
additional words after the issue number. Any help would be greatly
appreciated!
