Perhaps a desktop search or some other App is accessing the pst. You have I
assume checked running processes (Ctrl+Alt+Del) that no instance of
outlook.exe is running.
Perhaps boot into safe mode & then copy

I am transferring my Outlook files from Outlook 2005 running onXP to
Outlook
2007 running on Vista Home Premium. I have read all of the information
regarding transferring my .pst files to my new PC but I am getting this
error
message when I try to copy the files to a flash drive.

"Cannot copy outlook: The process cannot access the file because another
process has locked a portion of the file."

Outlook is CLOSED when I get this message.

My CD burner does not work and I am trying to copy the files to a flash
drive so that I can then move them to the new PC.

Any help would be greatly appreciated.
