I have read all the threads on 2011 Outlook Smart Folders .
I have also read the Microsoft tutorial.   I still do not understand how to use them

Is there a comprehensive article somewhere regarding building and using smart folders?

For example, I want to use smart folders for all emails from multiple sources for one client.

When I enter multiple email addresses in multiple panels of the smart folder they appear to
cancel each other out.  If I understood how to have multiple email addresses go into a Smart 
Folder that would be most helpful.
I don't know what smart folders are and — anyway, how to get rid of this nuisance?

In high priority, you click on it it loads up hundreds of emails. Are these copies from elsewhere? What the point?

I would like to create a Smart Folder for Inbox emails that I check as red "flagged".  I have successfully created Smart Folders for incoming emails by  "From" but can't seem to get the Flagged emails to go into a Smart Folder. 
I want 2 separate Smart Folders: 

1) All due -before- Tomorrow (i.e., Today & Before Today, or, i.e., all that are either Overdue or Due Today). 

2) Due Tomorrow (but not before or after tomorrow).

I've moved from Outlook 2003 on XP, and there you could type any logical day into any condition, any date field, any filter: "tomorrow" or "two tuesdays from now" or "three months from last monday" and it'd store and/or do the date math. But now there is no Tomorrow. Hellllllp! THANKS 
SMART FOLDERS
My save searches for SMART FOLDERS are not sticking in Outlook 2011 of Mac.  I have a edit the smart folder every day to exclude my DELTED, SENT, JUNK folders for a save search for TODAY's emails.  I like to look in this smart folder view as I move mail into various folders on my Exchange server and local "on my computer."  The feature works great, but I have to rebuild the FOLDER filter every time.  The Advance search keeps the "FOLDER IS NOT" search filter, but breaks the "FOLDERS" to exclude.  Mark
