Microsoft Office Outlook, View on Sent Items filtering on emails not responded to

1. filtering items not responded to

I would like to see a filtered list of emails that I have not yet responded
to. I can't seem to find such a property. Is there one? How can I do this?

3. View filter on mail items sent in the last 30 days

While trying to create what I thought was a simple view filter to show mail 
items sent in the last 30 days I've learned that Outlook doesn't accomodate 
this via simple configuration.  I tried doing an Advanced filter but I'm 
still constrained by the same limitations (e.g. last 7 days, last month...).  
I'm no wiz with SQL but it seems this is the only place where I can 
accomplish what I'm after.  I tried the expression below but it didn't pass 
the SQL parsing:

"urn:schemas:httpmail:date" >= today() - 30

How can I apply a filter that will show me all email sent in the past 30 days?

4. Sent Items Folder Not Responding

5. Sent Items there, but not there, no apparent Filter

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.

Am I missing something?
