1. Out of Office and Limited Access to Email Example. [Greeting] Thank you for your email message. I am going to be out of the office and will be back at (Date of Your Return).
I once left a kind of breezy, fun out of office message for “people inside my organization” that said the literal truth: “I am out of office this week at a mountain resort where I have paid many hundreds of dollars for someone to take my electronics away from me. I’ll get back to you Monday,” and a very normal and professional OOO for “people outside my organization.” Needless to say I returned to a message from a senior (but not, I stress, my boss or even on my team) colleague calling me out on it. People surely can make things their business.

I’d side-eye if an OOO for a couple of days off said that, unless someone was in an unusually time-sensitive role. But if someone’s out for long enough that there’s an alternate contact provided, that’s long enough for them not to be wading through missed emails when they get back.
But traveling for work, then I say “intermittent access” so that I only need to respond to the urgent emails and can ignore everything else for a few days.
