Lotus Notes R5 : Sauvegarde des emails

Marsh Posté le 28-10-2009 à 11:42:50

Bonjour

Je termine de mettre en place eGroupware pour un parc de 400 machines.
Une partie des utilisateurs utilisent Lotus Notes R5. J'ai pu exporter les calendriers et les contacts de Lotus notes pour les importers dans eGroupware mais il me manque une dernière chose avant de terminer le scenario de migration. Les utilisateurs doivent tous garder une copie de leur email. Hors, je ne trouve aucun moyen d'exporter les mails correctement depuis Lotus.
eGroupware utilise le serveur imap cyrus pour lire les emails.
Lotus Notes est configuré en imap également.

Comment pourrais-je procéder pour faire une copie des emails entre les 2 serveurs?

J'ai trouvé hier un script permettant l'export des emails pour Lotus Notes 6. Cependant, ce script ne fonctionne pas sous Lotus Notes 5.

Un spécialiste saurait-il contourner cette erreur due à l'incompatibilité de Lotus Notes 5 ?

je répond à coté : si tu as imap activé sur ton Lotus, pourquoi ne pas utiliser un outils du type http://freshmeat.net/projects/imapsync/
Le problème c'est qu'il faut connaitre le mot de passe internet de tes utilisateurs lotus mais tu peux probablement trouver ou faire facilement un script Lotus pour le réinitialiser.

Marsh Posté le 29-10-2009 à 15:45:41

Merci bcp, je regarde du coté d'imap sync.
Mon but est de pouvoir copier les emails depuis lotus vers cyrus, peu importe les moyens employés. Imapsync sera sans doute la solution retenue, d'autant plus qu'il doit permettre un synchronisation de masse et non utilisateur par utilisateur (ou en tout cas, ça doit se scipter simplement).

Encore merci pour cette astuce
