Finding the Reply to date in the Exchange server connection

Also there's an attribute called IconIndex in the Attributes Record column, you can also add a check where the received email has that flag value "MailReplied", so that you won't have to do a search for emails that weren't replied to.

Thank you both for the suggestions; I will attempt both shortly.  Ideally I was trying to create a calculated column from time of the origional email to the timestamp it was replied to.  This would allow me to monitor the response times under various conditions for a team email box.  These methods may allow me to get there with an extra step or two I hope.
