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.
It might feel strange to include happy client testimonials in your out-of-office responder, but doing so is easier than you think. A quick note that suggests they read the testimonials if they’re interested in a product or service you offer is an easy inclusion or postscript to your email. Just limit the amount you share to one or two.

Obviously, not every out-of-office is set for a vacation. You also need an out-of-office if you go on an extended business trip or to a conference. But instead of simply telling people you’re at a business event, why not use this opportunity to encourage networking of new business connections?
Every time I read it, it just gets funnier. On r/talesfromtechsupport, filter by top posts of all time, it’s on the first page. The punch line is … *chef kiss.
