As a “don’t try this at home” anecdote, last week we had an all staff retreat, and we were asked to put up away messages. I put a perfectly professional one up for outside email, but in a fit of whimsy, the internal mail triggered an away message that said “Why are you emailing? We are supposed to be paying attention to the retreat!” I figured, we were all at the retreat, so nobody would ever know. Of course, someone did email me 30 minutes before everything started, and triggered the message. Fortunately, he figured out it was an away message and thought it was funny.

I set my OoO for individual public holidays, because I know they’re not global, and I get emails from lots of different countries.
Have you ever had one of those most amazing kind of days; the kind of day that you will remember when you are old and gray and telling your grandchildren stories? Well, I seem to have those days quite often. In fact, if you’re seeing this message, it’s probably because I’m having one of those kinds of days today, and I’m not going to respond to your message.
