I have Office 2007 on a Windows 7 64 bit platform but I am still using Outlook 2003. I originally had Outlook on another computer and when I bought a new computer I decided to move all my data/pst files from the old computer to the new one over my network. I exported all my personal folders in separate pst files to the Public\Documents folder on my new computer. Then I imported them to the new installation of Outlook on the new computer. I left the old exported files in the Public Documents folder for months. A few days ago I was doing some cleanup and came across the old files and thinking I would never need them again I deleted them. After that whenever I try to open Outlook I get a pop up message telling me one of the deleted files can't be located. I click on OK (the only button offered) and an Explorer window opens to let me search for the missing files in a supposedly new location. I click on Cancel in the Explorer window and I have to go through the whole enchilada again for a second file it can't find. Finally when I click on Cancel this second time I am able to get into my mail and do whatever I want to do. Something in the registry or in an Outlook configuration file is calling for these deleted and non essential files but I can't find it. Can anyone suggest a solution?

I opened Outlook by jumping through all the hoops caused by some non existent files. I clicked File\Data File Management to open a small window showing all my data files and their locations. Surprisingly the two files I had deleted were listed there so I deleted the reference to them to fix the problem. The only question in my mind is why they were there at all. I only used them once as the import source for my Contacts and Sent Items folders.
