I just started using Outlook 2013 on my Windows 7 laptop. and I noticed that it's deleting items from my trash folder even though the box "empty deleted items folder when exiting Outlook" is unchecked. huh? It would make more sense if that box was checked but it is not. Is there another place to uncheck something so that my deleted emails don't get deleted?
and okay, why am I concerned about messages being deleted from the trash folder anyway? because occasionally I need to look for deleted emails. not very often but it has happened. so I keep some of the ones that I've deleted. well, not any more since I just discovered this issue in the last week.
