I hate when senders ignore the instructions in my OOO message. Usually, my message is something simple like: “I am out [Dates], returning to the office [Date]. Please contact Jane (jane’s email address) in my absence. General [department] questions may be sent to [general dept email address].” To me that says if you are sending me anything then I won’t see it until I return. If you have something you need to be resolved right away, you can contact Jane or send it to our department inbox (where it should be going anyway).
I had a colleague that managed to set up a rule for an OOO that would only get sent if you cc’d or bcc’d him, which basically said that all those cc mails would get automatically put in a separate folder and he may or may not ever read them – may the odds be ever in your favor basically.

Also, you need to know your audience if you are going to go eccentric. Alison mentions that this message is fine in their culture, but it wouldn’t npbe appropriate for my somewhat formal field. And even if your workplace in general is casual, you might be contacted by someone outside. (In a tiny provincial courthouse I served in the past, there is a story going around that in the 80s a junior but elderly clerk used to address phone callers as hun and sweetheart and generally speak very informally. Most people thought it was funny, and then the President of Supreme Court called and… he didn’t).
As the country’s situation gets better, we’ll reopen it and inform you through emails. In case of any queries, you may email at [Email] and your questions will be answered. I hope to see all of you once again in the office after the situation calms down.
