This header is as close as I can come to my problem. I have 2 "sent Items"
files in Outlook 2003. One contains material from 5-May-09 to 22-Dec-09. It
is stored under the Inbox. The second has material from 5-May-09 to
13-Nov-09 and is in a folder of its own at the bottom of the list.

Issues:
Why does this occur? Does it have something to do with backup?
How do I recombine them without creating duplicates (I don't have Access)?
How do I prevent it from happening again?

Thank you for your help and Seasons Greetings
