In our company it is very much the norm (though some don’t and it’s not looked down on. It’s just we kinda know every handles the ridiculous amounts of email we get in different ways that suit them). And it’s the norm of the people who so to put that in there because 1. if you go anywhere north of where we’re at, you’ll get zero reception and 2. other people we work with know you normally do.
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).

We hereby inform you that due to the prevailing hazardous situation of [X], it is decided that all our offices in the city [X] will remain closed. At this time, it would be very difficult for all of you to come out of your homes for office as there is unrest everywhere and one never knows when his turn will come. So, by caring for the safety of all of you people it is the mutual decision from all of us that our office will remain closed during this period. As to open it in this prevailing situation is not less than a risk. So, it will remain closed for a long period of time.
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.
