I agree! I’m in HR and all I can think of when I see funny OOO’s from people is, “How big of an a$$ are you going to feel when someone emails you about needing time off for a funeral and they get this nonsense back?”
I have a confession to make: I haven't recorded a new voicemail greeting in nearly a decade. Since then, I've (hopefully) become more articulate, poised, and self-assured. But hear my voicemail recording, and you'd think I was still new to the work world, a little unsure of myself — and probably not an authority.

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).
Next time you’re setting up your vacation responder, consider using this quick guide to help you be more creative and professional when needed. Use your out-of-office message to inform, assist, or delight the email sender. It will be a pleasant exercise for you and might make them smile.
