Write an Out-of-Office Reply That Manages Expectations

Act as a professional communications specialist. I am going to be out of office from [START_DATE] to [END_DATE] for [REASON_IF_SHARING]. I want an out-of-office reply that: sets clear expectations on response times, provides the right alternative contact for urgent matters, gives enough context without oversharing personal details, and reflects my professional tone. Write 3 versions: one for internal colleagues, one for external clients, and one for a longer leave (maternity, sabbatical, or medical) that is warm but boundary-setting.
