But this absence of basic travel cybersecurity is a problem. Email is the number one threat vector for socially engineered attacks. An automatic reply message not only sends the information to designated contacts, but it also bounces back to people who send phishing emails. Threat actors use any details found in OOO messages to craft targeted social engineering messages. Well-targeted messages build trust that threat actors take advantage of.
In spite of your best efforts to notify people ahead of time, not everyone will get the notification that you're going to be shut down. Make sure that you: Post signs about the shutdown and when you will be back Change your voicemail message and have a plan for what to do if your voicemail is full: will it notify you? Is there an alternate number to call? Put together an "out of office" email that lets people who attempt to contact you know when you will be back Make sure you have a call tree for emergencies, and that everyone knows who he or she will be responsible for calling in the event of an emergency

Hah! Maternity/parental leave is often 1 year here, so there is zero expectation you will read or “catch up” afterwards. We keep our email addresses during where I work (Canadian government), so it’s standard to put an OOO that just says “on parental leave. Please contact X instead” with no reference to actually reviewing any of those emails, and often not even a projected date of return since people often flex their return date or take extra time, or just return to a different position entirely (out of choice).
Hey, Thanks for your email. I’m not in the office and am on a family vacation. I assure you that all your emails will be answered as soon as I return to the office on [date]. Kind regards.
