Sending a MAPI email via Java ( or C# )

Question

I have a java program that sends some emails currently using SMTP. I have a customer whose corporate network is locked down and only allows sending of emails via the MAPI1 and MAPI4 protocols.

After looking around on the internet I have been unable to find any examples of sending an MAPI email from a Java program. If we have to pay for some 3rd party component its not the end of the world, but free is obviously better :)

Another point to add is that if the task is much easier in C# then there is the possibility of creating the send email functionality in C# and calling the C# program from the Java main application.

Please let me know if you require anymore information.

Answer 1

All of the following can send mails via MAPI from Java:

• http://www.codeproject.com/KB/IP/CMapiEx.aspx
• https://github.com/briandealwis/jmapi
• http://www.moyosoft.com/joc/ (commercial)
• http://www.dimastr.com/redemption/ (commercial) together with http://sourceforge.net/projects/jacob-project/ (COM bridge for Java)
• http://www.moonrug.com/features.html (commercial) (no longer appears to exist)

You will usually need the MAPI COM components on the local machine and always the credentials for the MAPI connection/Exchange account!

Since I am not sure what you mean by MAPI4 versus MAPI1 I suspect that you might mean IMAP (there is a V 4 of the protocol) which is quite different from MAPI - just in case the following are Java options for IMAP:
