Huge pet peeve – several of my coworkers still have COVID-related out of office notifications. I didn’t find them necessary in the first place, since everyone was still working from home and should have been checking emails normally, but it’s especially weird now that we’re officially back in the office a couple of days a week. It feels like they’re making a preemptive excuse for responding slowly. I’m surprised management hasn’t said something, honestly.
Thanks so much for your note! I’ve packed away my makeshift office for the week in order to go nowhere and do nothing. I may be dipping my toes in the tub instead of the ocean and making my favorite Smitten Kitchen recipes for myself rather than indulging at a fancy restaurant, but I’m still trying to disconnect and recharge.

I’m currently out of the office between [DATES], as I’m attending the yearly WordCamp. Perhaps you will also be there, and we can meet in person.
I wouldn’t be offended or consider saying anything to anyone who included this in their out of office message, but even as someone who is in a religion that forbids use of electronics on most holidays, I still think this message is 1) TMI; 2) doesn’t convey what it needs to convey unless you are explaining that you don’t use electronics during holidays, in which case you can just include that you won’t be checking email without including the religious explanation; 3) would come across to me as inclusion of personal information I don’t need, which would therefore strike an unprofessional tone,and I wouldn’t understand why you felt the need to include that info. How about “I’m out of the office without access to internet or email until (date). If you need assistance before this date, please contact…” Like I said, I think your colleagues are overreacting, but in general I would advise to leave all personal information out of your auto-reply — vacation, medical leave, religious observance, etc. — people do not need to know why you are out.
