My boss will be out of town and he wants all of his emails deleted after an out of office is sent. A quick test suggests that if I set an out of office and add a rule: Delete (don't accept message), the message being refused happens first so the out of office is never sent.
I could add a rule to have it filtered to a separate folder and then delete the folder at the end of his vacation but that would likely sync with his Outlook and he'd see the folder. This might still be the best solution, however I am hoping that I can the message deleted.
This is using Lotus Notes 9 and I have access to his Outlook or webmail client.
