Anybody that might need me that quickly should have access to my calendar and can see I’m in a meeting. Anybody that can’t see my calendar shouldn’t expect a reply in an hour unless I’d said I’d be available or something.
Here, we’ll go over what’s required in an out-of-office email responder or email greeting, as well as a few ways you can jazz up your out-of-office message (and potentially making your colleagues wish they thought this up first!)

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.
