I've got a folder in my inbox for sorting out-of-office and vacation messages from my coworkers. It's nice and convenient to arrange by "From" - keeps everyone encapsulated in their own collapsible list, and I can just expand it when I need to access a certain person.
When I first created the folder, everyone's list stayed closed by default. However, as I add messages from new people, their lists stay open by default - if I collapse a person's list, leave the folder, and come back to it, that list is expanded again.
I tried changing the Arrangement style today. Now, all lists are open, and they default to open anytime I re-enter the folder. This is completely unacceptable, as there are hundreds of these messages with more coming every day. I just want to have a list of people, then expand the list when I want to see what's inside it.
How do I accomplish this behavior? I can't for the life of me figure out how I got the lists to stay closed by default, and any attempt to fix it just seems to make it worse.
As an aside, I desperately hate outlook.
UPDATE: View >> Arrange By >> Make This the Default View is also ineffective. Maybe it's time to rebuild the database?
