I agree that the reasons are not relevant. But at my last company, a coworker had overly short out of office messages. Examples: “out of office today.” Or “out of office until Monday.” With no additional information about coverage, etc. Those always felt overly curt to me and made me wonder, is this person okay? Was this OOO planned or are they on the verge of a mental breakdown? (It was a very toxic culture so this wasn’t out of the question). I would be curious to hear others perspectives on this. Is too little information just as bad?

Boss would put up an OOO when attending an event off-site, but would still be answering their emails, which meant that I would get “Boss said you were the correct contact, can you help?” Inevitably, I would respond and, two hours later, Boss would too, cc-ing me on the original email in which they shared the exact same info I had earlier that day. It was MADDENING.
There were a lot of bilingual staff at my last job, and they always did their out of office messages in both languages. But who knows, maybe the Welsh translator was in a rush and forgot. An agency that handles government translations like road signs might be expected have such rules. On the other hand, never underestimate the boneheadedness of the monolinguals. Especially English ones.
