I had a boss who was mad if I put his full name on my OOO. I was his deputy. He said people should know how to contact him if I just use his first name. He thought the public would get his info (public-facing office but we didn’t correspond with the public at our level, of course). It made me feel very very silly to comply.
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).

If you want people to remember that you’re away, do something humorous or different, suggests Misner. “The normal out of office message that says you’re not available and you’re on vacation is fine, but not memorable,” he says.
Since holidays occur throughout the year, there is no one ideal time to send a message. For the winter holidays, we recommending sending your well wishes early in December. In general, if you can send your message before people get busy with the holiday, then it will have a larger impact.
