A literary agent I follow told the story of a long argument her autoreply had with a would-be author. She’d set up the outbound email while out of town and apparently an author who queried her with his book took offense to it. He replied back in frustration that he didn’t get a personal response. Her autoreply sent back another automated message, which he then in increasing anger kept responding to.
Above a certain level in my agency managers have to designate an official delegate when they’re out, which can easily result in out of office messages like what you’ve listed. Not the most elegant, but clear and useful!

But it seems a bit too chock full of dismissive, thinky veiled put-downs really. I wouldn’t want to work for someone would lump the people who work for them as competent humans (oh-em-gee, thanks), is that the best they can do to describe people? Oh wait….they look out for her (is she a princess) and each other (should I start applauding now?). No one needs to call me or anyone else a rock star, best teapot decorator in the multiverse, or amazing humans all the time but the best she could crank out was competent + humans. I get the attempt to be witty but it’s really sad that she isn’t more generous.
I used to work at a place where we would occasionally send reports of network misuse that sometimes included inappropriate images the user had stored on work devices. One person had an email system that was somehow set up to make any attached images the profile pic for that account. So she would end up with random pornographic images as the profile pic whenever she received reports from us. She said she had no idea how to change it and could we please help? Since she was not part of our company, and I have no idea how that could even happen, I just started sending her kitten pictures after every report that included an image. Problem solved.
