En fait, Outlook Express garde une trace des emails téléchargés. Voici donc la solution : effacer le fichier Pop3uidl.dbx de votre répertoire de stockage et tous les mails sont à nouveau téléchargeables.
Voici l'info en détail :
After using Gmail strictly on the web, I decided I wanted to download
all my archived messages into Outlook Express for viewing offline,
including the sent ones. If you're having trouble doing this, try the
following:
1) Mark all your archived messages as unread and send them back to the
inbox (including the sent ones).
2) Set your Gmail POP access to "Enable POP for all mail (even mail
that's already been downloaded)".
3) Assuming you are already using the correct settings in Outlook
Express, start OE and try retrieving your mail.
4) If you're not getting all your messages, locate the folder where
Outlook Express stores your messages (look in the Tools menu under
Options / Maintenance / Store Folder), close OE, go to that folder (it
may be a hidden folder) and delete the file "Pop3uidl.dbx", which logs
your mail downloads.
5) Restart Outlook Express. It will generate a new Pop3uidl.dbx, and
download all your Gmail messages.
