Outlook Express e mail message transfer to Windows Live Mail

My question is specifically addressed to the issue of folders and sub folder transfers from Outlook Express (OE) to Windows Live Mail (WLM). I have been able to locate all my .dbx files for OE (now in a separate folder on my desktop including the critical folders.dbx file) and also my contacts that are safely in a folder in the .csv format. The migration to Windows 7 Live Mail (WLM) went "flawlessly" for the contacts. However, not so "flawless" for all messages. Although the migration worked to the extent that I now have 5364 messages located in the folder called "Unread e-mail" and 3595 messages in the folder called ?Unread from contacts?, none of the 200 plus folders and sub folders that used to be readily available in OE managed to make it over to WLM. I have read in some posts on the web that the transfer may get hung up on the fact that the OE stored top level folder property is "read only" blue check mark and I have read how to change that and then try the import. The removal of the "read only" actually worked well when I was migrating from OE to Windows Mail in Vista since all folders and sub folders made it across in the transfer. However, I am unable to achieve similar success in migrating OE messages over to WLM. I can certainly use WLM for e-mail; however, it is the loss of the folders that is annoying and perplexing. I have also read on some sites that the size of the deleted items dbx file might also cause problems; however, in all instances, my dbx and bak files never exceed 2 gb although some come close. I would also note that when the import of the messages from OE to WLM is in progress one can see all the folders moving over; however, they never ever appear in WLM. There is nothing, zip, nada under imported folders. I just find it quite amazing that Microsoft makes this entire migration process so mind boggling and fraught with peril that the average user must just throw their hands up in total frustration.
