A few hours ago a deadline was about to pass. I had promised someone I would send them the final draft of a file before they got into their office this morning. I also knew that I would not be available to re-send it if there was a problem because of a previous commitment. I wrote the e-mail and pressed send. Immediately the following window appeared:Wow… how often have you done that? ‘Hey I am sending you this file’ and then you forget to attach it? Sometimes you catch yourself and sometimes you only realize it when the return e-mail of ‘what file?’ comes through. Fortunately Outlook 2013 saved me in this case – I was tired and likely would not have realized it, and my colleague would have had nothing to work on this morning. Thanks Outlook!
