Very good app

I needed to backup my outlook for windows mail messages and contacts to keep a copy on my Mac, and had been unable to open them before finding Klammer. This app delivers what it promises, is very simple and works very well. The only thing missing is mass import in mail, so that sorting messages would be easier, but except for that its worth its price if youre looking to open outlook files on a mac.

Très Bon ! Fonctionne très Bien !! Merci.

Très Bon ! Fonctionne très Bien !! Merci. Tout est dit. Thank You.

Très bonne app et très bon support

Quelques petits problèmes rencontrés (normal, vu lutilisation intensive que nous faisons de cette app) mais un support très à lécoute et réactif. A acheter les yeux fermés.


Enfin un logiciel qui me permet de lire les formats .MSG sans problèmes ! Ouverture des fichiers sous une interface graphique très ressemblante à Mail (pas comme les autres programmes que jai pu trouver sur le net qui soit nétait pas stable, soit maffichais la moitié des textes, avec une interface type textedit donc pas très fun) Claire, simple et efficace. Rien à rajouter :)

Pour éviter Outlook

Si vous êtes (comme moi) dans un environnement Exchange, Klammer vous évite probablement Outlook pour ouvrir les messages winmail.dat, et les ouvre bcp plus vite

Bug sur la maj

la maj devant corriger des bug reste coincée et nabouti pas. je reste tjrs avec une maj en suspens, svp développeur allez jusquau bout. merci Vite une nouvelle maj simpose

Application inutile

8€ gâchés par une application qui ne fonctionne absolument pas pour ouvrir des fichiers .msg. Il devrait y avoir moyen de se faire rembourser dans ce cas
