Something about it gets my goat up! Like she’s working and emailing me about things she wants me to work on, but her OOO is telling me to buzz off coz she’s too busy to get to my emails. Also she still has it set up and we’ve been in lockdown for over a week. How long does she intend to have her OOO triaging everything and making excuses for delays? We all know there’s a lockdown, that’s why everyone is scrambling for their events to be rescheduled – it just comes across as very self-important at a time where everyone is under stress. No one else in the organisation has this so it seems very bizarre to have an OOO while still working!
An out of office message is a compact text that conveys the most important facts: How long you’ll be unreachable, when your contacts can expect an answer, (optionally) the reason for the absence, and, if necessary, a personal note. A referral to another email address, e.g. to one of your colleagues, is often helpful or even necessary.

Have you sent a proper farewell email to the whole office, thanking everyone and wishing them well?
A retired small town newspaper guy once told me about the first time the publisher went on vacation and left him in charge (this would have been in the 80s). The publisher told him “Don’t call me unless the building burns down, and even then, don’t call me until the fire is out.” Good example of management setting vacation expectations.
