Access to IMAP Inbox in JavaMail with defaultFolder() results in "Bad folder name"

Is it possible to cast javax.mail.Folder to IMAPFolder?

When casting in Netbeans, there was no error. Until the next line where I tried to open the folder 

                    IMAPFolder ff = (IMAPFolder) store.getDefaultFolder();                        
                    ff.open(Folder.READ_WRITE);

I get BAD folder name on the logs:

[Thread-4] ERROR com.mansueli.mailtester.IMAPController - ERRORjavax.mail.MessagingException: A11 BAD [CLIENTBUG] SELECT Bad folder name. sc=Ttg5C13MBa61_091355_17p; nested exception is: com.sun.mail.iap.BadCommandException: A11 BAD [CLIENTBUG] SELECT Bad folder name. sc=Ttg5C13MBa61_091355_17p [JavaFX Application Thread] ERROR com.mansueli.mailtester.IMAPController - ERROR it wasn't possible to connect with IMAP properly ERRORjavax.mail.MessagingException: A11 BAD [CLIENTBUG] SELECT Bad folder name. sc=Ttg5C13MBa61_091355_17p; nested exception is: com.sun.mail.iap.BadCommandException: A11 BAD [CLIENTBUG] SELECT Bad folder name. sc=Ttg5C13MBa61_091355_17p A11 BAD [CLIENTBUG] SELECT Bad folder name. sc=Ttg5C13MBa61_091355_17p

I want to open it as an IMAP folder but only have the store.

Store store = session.getStore(imapstore);

Solution

  • The defaultFolder() is not yet the inbox.

    Try this instead::

     IMAPFolder ff = (IMAPFolder) store.getDefaultFolder().getFolder("inbox");                        
 ff.open(Folder.READ_WRITE);

    Good Luck!
