Java EE (Java Enterprise Edition) General Discussion

hi,

I want to access a shared mailbox (NOT FOLDER) via Javamail API (1.4.5) using IMAP(s) with plain logon. The mailserver is a Exchange Server 2010.

User: user1 (user1@domain.com)
pwd: xxxx
shared mailbox: shared_MB@domain.com

Properties:

mail.imaps.socketFactory.port = 993
mail.imaps.starttls.enable = true
mail.imaps.socketFactory.class = javax.net.ssl.SSLSocketFactory
mail.imaps.socketFactory.fallback = false
username = user1@domain.com
password = xxxx


I´ve managed to get access to the user1 - mailbox:

Session session = Session.getInstance(properties, new ExchangeAuthenticator(username, password));
session.setDebug(true);
Store store = session.getStore("imaps");
store.connect(imapHost, username, password);

--> this works just fine! But now i want to access the additional mailbox by changing the login-String:
username=user1@domain.com/shared_MB (user@domain/additional_MB)


--> unfortunately I´m getting an "NO AUTHENTICATE" message:

DEBUG: setDebug: JavaMail version 1.4.5

I was able to get access with Thunderbird and also with the Exchange OWA-Client, so I think there is something missing in my code...
or is it just impossible to get access to a different mailbox using javamail and plain-auth?

Thank you in advance.
