So, skip saying you are in Las Vegas attending your favorite conference with the hopes of seeing a show or finding some time to play the slot machines. Even if other colleagues are going to the same conference, just say you will have limited email accessibility for the week and will return the message as soon as possible. Rather than an Instagram post with the view outside your window and naming the hotel as soon as you arrive, save the photos for a limited audience upon your return. Finally, consider adjusting your settings so that your out of office message is sent to contacts only.
“When I got there and found out the bungee was 134 feet high I got terrible cold feet, but I felt that since I wrote it, I had to do it. So I did. It was terrifying and indeed a lesson on making bold claims in a public way!”

About the “overshares”: You linked to a previous column that mentioned this point, “Sometimes the over-sharing of plans can even come across as suspect — similar to how when someone’s calling in sick with genuine illness, they usually just say, ‘I’m going to be out sick,’ but fakers will generally give you a long list of overly specific symptoms, like they feel they have to convince you.”
Yeah, announcing you were going to delete emails unread and expecting the sender to resend when you return would NEVER fly in my office. I’d get executive complaints about that, especially if it went to a client or outside party – if a client can’t reach you, they will reach out to someone else who may not work at your organization and you lose business. I feel like this delete-it-all philosophy would only work for an entirely internal role where timelines are more relaxed, and even then, I feel it’s a bit unprofessional to foist your own catch-up work onto others, especially if they’ve been backfilling for you while you were OOO.
