The example above (which comes from NY Times) may not take advantage of some of the tips we mentioned, but it’s great because it’s so short. Due to its absent-minded straightforwardness, such a message can be perceived as a real, non-automated reply — as if you were so busy that you only carved out a few seconds to type these five words.
Q. If I am not impacted by this winter break schedule (because I work at UTMC, for instance), do I receive additional paid days off per year?

I have followed these steps on my work iPhone. I have driving mode set to manual and to apply to “allow calls from no one”. DND is on manual and I have turned on driving mode (which automatically turns on DND) in the Control Center. But when I send a test message from my Samsung personal phone, I am not getting the auto-reply.
My OOO is almost always “I’m out of the office and will be returning on x date.” My email sig has instructions along the lines of “for questions on x, email this list” for a couple of the more common areas people would contact me about that might need an urgent reply (as the lists go to more than just me, obviously), but most people have finally figured out to contact those lists to start with, anyway. If I were in the middle of a project or something that needed to be moved along in my absence, the project teams usually know when we’re out, but I’d put a back up in that case, if needed, but generally there’s not much to be gained by a longer OOO from me.
