Hello, I’m out of the office until [DATE]. However, I will be taking periodic breaks from binge-watching everything I’ve missed to check my email [once per day/every evening/occasionally] while I’m away. If this matter isn’t time-sensitive, rest assured that I’ll respond when I’m back in the office. But, if this is an urgent request, please resend any messages that require my immediate attention with a subject line of “URGENT: [Original Subject]”. All the best.
If you have critical projects that can’t wait until you return, offer a communication option like text messages, suggests Reeves. “I have found, to my delight, that people really are judicious about texting you while on vacation,” he says, with one caveat. “Don’t put your mobile number in the away message. That way, only people who have your mobile number can text you. And those are the ones you care most about.”

You should use your out of office email whenever you’re going to be away from the office – whether it’s for a day, a week, or even longer.
No one thinks much about cybersecurity while traveling. However, email security company Tessian warns the out of office message actually plays right into the hands of threat actors and cybercriminals. It’s a social engineering attack vector that no one thinks about. The out of office message is ubiquitous and handy. But if it includes any personal information at all — such as attending a funeral or going out of the country — attackers have all the information they need to impersonate the person who is out of the office, without the attacker having to do any real work.
