I am trying to find a relatively quick way to filter or search an Outlook profile for emails sent by the user that were never replied to. I haven't found much about this on the internet other than options to flag the emails when you send it to set reminders. I have also seen a mention of searching in Outlook 2010 advanced settings for conversations that are empty but I don't think that will work.
I am looking to sort through about 400 emails that were sent to an individual that did not receive a reply and going through them one at a time obviously would be very time consuming. Any help is greatly appreciated!
Outlook 2007 or 2010
Exchange 2007 (not using POP or IMAP)
