Javamail rename folder

[Himanshu Rawat]

Hi,

I am trying to rename a folder using java mail api but unable to do so.

Below is the pseudo code

Store store = session.getStore("imap");
store.connect(getIMAPHost(), getIMAPPort(), getEmailId(),getDecryptedEmailPassword());
IMAPFolder folder = (IMAPFolder) store.getFolder(folderName);
if ( folder.exists()) {
     if ( folder.isOpen()) folder.close(false);
     Folder abcFolder =  store.getFolder("abc");
     
     boolean folderRenamed =  folder.renameTo(abcFolder);
     System.out.println("folderRenamed :: " + folderRenamed );
}
     store.close();

Its always returning false, failing to rename the folder.

Please tell me what wrong I am doing here and how to make it work.

We are currently using javamail-1.2ea2 version.

Thanks,
Rawat

For starters, use a recent version of JavaMail. Yours is more than 10 years old.

Does the underlying OS allow renaming?

Ok. I will try with upgraded version of JavaMail.

OS allows everything if permissions are there.

I wouldn't think that OS permissions have much to do with renaming a mail directory. Could be, I guess, but a mail server based on file system storage creates, renames and deletes files all the time, so it needs those permissions to function.

Well, we don't know from the OP if this is a stand-alone Java application, or a web-application.

If web then the server runs under an account, which may be passed to the IMAP server.

Returning "false" indicates that the rename failed, and it looks like no other data is available.

If this is M$ Exchange, may be possible to look at the logs or events on the host.
