I don't know the 2007 version, but I would be amazed if you can't move individual files around.
I have started to recover from a HD failure. Part of the restoration of data requires me to "merge" Outlook email from prior to the crash with Outlook email subseqent to the rebuild.
When I try to drag and drop an Outlook folder from Local Settings containing .pst folders from one user to another Windows warns me that the dragged folder will replace the target Outlook rather than merging contents with it.
How do I get the folders to merge rather than one replacing the other?
