That’s so weird! Email is the correct way to reach a teleworking person, that’s the worst place for an OOO message. Stick an OOO sign on your physical office door, by all means!
Hello, It’s that time of the year. The time where I save up all my vacation (4 weeks) and spend it on one epic adventure. Where am I? [COUNTRY], the land of magic realism. And I’ll be completely disconnected. In fact, I’ve asked [NAME] from IT to change my password so I can’t check my email at all. #vacationorbust. If you have any questions about [PROMOTION] or anything else, get in touch with [NAME] at [EMAIL] If you want to talk about the hottest job opening at [COMPANY], [POSITION/TITLE] get in contact with our People and Culture team at [EMAIL].

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.
Yeah, it’s very strange. I understood changing voicemails to explain that the line can’t actually be answered, but someone is checking the messages and will respond (though that was also only an issue for the first few months), but they had no reason to even mention it for email. I started my job 3 months into lockdown, and by that point, procedures were in place to pretty much allow us to operate normally, albeit with a lot more done electronically than before.
