I now have newly installed Outlook 200
The confusion for me was in not having the exact term "Mail Received" available to me when I did a search or Find for old mail in the Inbox
I recall in my old version,(2002? not sure) there was a category called Received Mail when I did a search or Find. As in Find "such and such" in "Mail Received." Then I could arrange that by View
Your reminder of the category " Inbox" clarified that Inbox and Received Mail might be the same thing here. I did a search for old mail in "Inbox" and indeed, all old mail was available.
In the Microsoft Help...there were no directions for clarifying this. No directions I could find to help, or maybe my concepts were blocking my hearing directions. I kept looking for Mail Received, or Received mail. Thank you for the help.
Carl.
