Sent Items Folder For Multiple Accounts In Windows Mail

Okay, here it goes. I first started using Windows Mail when I bought a new computer with Windows Vista back in January '09. I have four email accounts which I transferred over from an Outlook Express backup that I did before getting rid of my old computer. Windows Mail automatically set up a set of folders (Inbox, Outbox, Sent Items, Deleted Items, Drafts and Junk E-mail) for each account, each with a different color scheme, similar to Windows Live Mail. My hard drive crashed in June and I'm just now setting things up again with the new hard drive installed. I tried restoring my email accounts from a backup I had but now Windows Mail won't automatically create folders for each account. Instead, I had to set up separate Inbox folders with message rules for each account. However, all the accounts are still sharing the Outbox, Sent Items, Deleted Items, Drafts and Junk E-mail folders. Is there a way to set up a set of these folders for each account using message rules? And also, why did Windows Mail do that automatically for me the first time using it - could it be that the information came from an Outlook Express backup originally?
