Sent Items there, but not there, no apparent Filter

[NickB]

Am I missing something? Outlook 2000. In Tools-

Options... the box is checked to Save Mail Messages in

Sent Items Folder, and in the Options of a new mail
message, it says to Save it in the Sent Items Folder.
Yet, after the message is sent, we don't see it. We do
see emails up to about a week ago, nothing since then.
Yet if we do an Advanced Find, we find the messages, and
it says they are in the Sent Items folder. There is only
one Personal Folders, no Mailbox. Upon opening the Sent
Items, we sort by Date and Subject, but still can't see
them. We go to View->Current View (Sent View is selected)-

Customize Current View and Filter says Off.
