Outlook Express have to be closed during the restore procedure. If it is running, you'll get a warning message. Please close Outlook Express or other programs that use OE (MS Messenger, etc.), and wait until the operation will end.
You will get Operation completed message after the restore procedure completed successfully, unless the operation was canceled or some serious errors occurred. If you get Operation canceled message at the end of the procedure, please check if you have enough free space on you disk and redo the restore procedure.
Note: Successful restore is guaranteed only if the current version of Outlook Expressis the same or higher used during the backup. Also it is strongly recommended run Outlook Express at least one time before restoring on a new computer.
