I've recently had to move my Live Mail accounts from one failing computer to another, which I did by copying the Windows Live Mail folder from one to the other. All looked well until I came to review the Storage Folders and found that the e-mails in the Imported Folders / Local Folders / Sent were no longer sorted by 'To' and this didn't appear in the Sort List. Instead they were all showing as 'From' the relevant account.

Moving a few e-mails into the Storage Folder / Sent Items folder now showed 'To' in the sort list, but creating a sub folder in Sent Items and moving the e-mails there reverted back to a 'From ' sort.

Is there a way to add the 'To' sort feature back into the sub folders in the Imported Folders?
