Why doesn't status change to auto-responded if recipient's out-of-office replies are turned on?

Issue

Sender expects that the Recipient status will change to AutoResponded when recipients have Out of Office emails set up.

Solution

This is expected behavior. The Sender will not receive the Out of Office reply. This is not considered a (bounce/auto-response) because the email is accepted by the remote mail server and is not triggering a SMTP failure. It is considered a successfully delivered email and therefore the recipient status will not update to AutoResponded in this particular scenario.
