Have you ever been part of an email chain that goes back and forth so long that the subject of the message no longer matches the topic being discussed? Someone you are talking about yesterday’s conference call with might throw in, “Oh, by the way, my return flight number is 191…” and all of a sudden you have important information with the subject line of “Re: Yesterday’s Call.” There is a hidden feature in Outlook that allows you to edit the subject line for the necessary email. Simply double-click the message to open it and click in the subject line to edit it. Type in your new subject, hit ‘Enter’ and accept any error message that may have popped up and you are done. I was quite surprised to read about this, as I have only changed subject lines when replying or forwarding in the past.
