I am using Outlook 2007 (in Office 2007). (Windows XP Pro SP 3 – fully up to
date with all updates and patches).

I am very picky about the cleanliness and organization of my folders.

I can't figure out how to empty 2 or more "Deleted Items" folders. I use
Outlook to manage multiple e-mail accounts. Each account has its own
“Deleted Items” folder. When I check e-mail in account #1 (default account),
#2 or #3 and I delete an e-mail from its “Inbox”, it goes into its respective
“Deleted Items” folder. When I exit Outlook, the “Empty Deleted Items on
Exit” seems to only works on the Default account. How do I get it to work on
multiple accounts, for multiple “Deleted Items” folders?

The only way I can empty the other (account #2 or #3) “Deleted Items”
folders it to perform a right click on the “Deleted Items” folder and select
Empty “Deleted Items” Folder”.
