Thanks for sending the required links where i got the steps of establishing connection between java and MSOutlook. Please tell me one thing is Outlook Express amd MSOutlook are same. I've to connect Outlook Express with java , then should I follow the same steps as i've done as with MSOutlook.
You didn't say how you implemented the connection between Java code and Outlook, but in any case Outlook and Outlook Express are quite different applications. It's possible that their file formats are similar (if your code works by accessing files), but in general I wouldn't expect something that works with one application to work with the other.
