Not really because every pop3 account you set up will have its own set of subfolders (Inbox, sent, etc.). However it may be possible to have all your pop3 mail forwarded to one of your accounts and then set up only that one pop3 account in WLM. This has the problem of causing the default send account to be the same for everything. One way to receive everything in one account, but have a "dropdown" choice for sending, is to set up the other accounts as imap on WLM. All imap accounts use the same group of storage folders, except for downloading received mail. You still need the one pop3 to download and delete from server at the same time and also to use message rules.
