I regret to say that I am currently out of the office due to vacation. During vacations, I will have limited access to email and won’t be able to respond to you timely. I will be having my laptop and Android phone with me and try my best to respond to any urgent email. If you feel that your query is urgent, and you need a quick response to send me an email on [Email].I am leaving behind my assistant whose name is Lewis. You may ask him anything regarding the official work otherwise I will respond by email for the time when I come.
I wrote the above comment off the top of my head. I wish I had time to rewrite and edit it. I would have changed “their goldfish” to “a spider they accidentally stepped on”, and would have added more detail to the story of the sister’s death (e.g. “her Pomeranian yapping” rather than the less descriptive “her dog barking”). Unfortunately, I could not do the thorough writing job required for that comment because someone close to me recently … – The person whose out of office advertised his gig on the weekend, for anyone in travelling to [city] – The people in a certain department who have taken to saying things like “if you really need to contact me, call 000-YYY-XXXX where Y is the square root of [insert numbers] and X is the year plutonium was discovered.” – The ones where people have an auto response saying they only check their emails once a day between 1-2pm – “I’m on research leave and I may be slow to reply.” (Whereby it is guaranteed they will reply immediately, because academics do not *really* take breaks).

I’m currently out of the office for the holidays. While you are reading this response, I am probably: Trying not to laugh at my [relative’s] corny jokes Trying not to get pissed at my [relative] asking me why I still don’t have a boy/girlfriend Attempting to explain my career to my [relative] for the 800th time Trying not to get hungry (I’m probably busy stuffing my face with cookies)
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.
