When our DocuWare was originally set up, the company that did the work didn't set the users document trays correctly.  I ran the following query 
SELECT U.name, U.email, CAST(U.settings.value('(/DWUser/@defaultWebBasket)[1]', 'VARCHAR(50)') AS UNIQUEIDENTIFIER) AS defaultWebBasket, C.NAME
FROM 
    dwsystem.dbo.dwuser AS U
LEFT JOIN dwbaskets.dbo.DWCABINETS AS C 
    ON CAST(U.settings.value('(/DWUser/@defaultWebBasket)[1]', 'VARCHAR(50)') AS UNIQUEIDENTIFIER) = C.GUID
to determine which basket tray is the user's default.  Example, for John Doe - when I look at the document trays, I don't see his.  Looking at this query he has "WEB_BASKET_BUFFER_90".  If I go into configurations and look for "WEB_BASKET_BUFFER_90" - it is not listed.  How do I go about fixing this so I can do configurations for Outlook Email so the user can upload to their tray before they store it to a file cabinet?
