I had to reinstall Windows and before doing so, I exported my different accounts and messages.  I tried now to import the accounts but get the message "the import could not be done due to an error (in French: l'importation n'a pas pu être effectuée car une erreur s'est produite).  It does not work for any of my accounts.  I can import the messages, but I have to select individually each folder, and the messages are then stored on the harddisk and not under the account.

Is there any way to get my accounts imported w/o having to configure them again manually and import all messages by folder / sub-folder ?

Thanks for your help.
