Modules: Importer les messages d'Outlook 98 |

Importer les messages d'Outlook 98.
La nouvelle bibliothèque CDO Reference Library
disponible avec Outlook 98
nous donne plus de contrôle sur MAPI. Par exemple, on peut
utiliser CDO pour importer les messages d'un dossier de email à une
table locale d'Access.
Voici un module de classe qui automatise cela pour vous. Ne pas oublier de
cliquer sur la référence (Menu: tools, references... ) Microsoft CDO 1.21
puis couper-coller le code dans un nouveau module de classe
Noter qu'à ce moment, cette classe n'importe pas
d'information relative aux pièces jointes (attachments).
