We have tried to convert EML to MBOX using Aspose.Email for Java 18.11 and it is converted successfully with no “?” marks found in subject. Please have a look at the generated MBOX file here inbox.zip (3.6 KB).

Moreover, it is requested to please try with latest version of our API and let us know if issue still exists.

We are sorry for inconvenience.
We are unable to find any “?” marks in any of the EML or generated MBOX file, please have a look at the screenshots EML_No_Marks.png (68.0 KB) and Converted_mbox.png (13.0 KB)

Moreover, it is requested to kindly share what platform are you using and which application is being used to view EML and MBOX files. So that we could investigate further.

Please find the MBOX file here inbox_new.zip (6.7 KB) and check it. This is exported from “Original file.eml” using Aspose.Email for Java 18.11 and the following code sample is used.

        FileOutputStream writeStream = new FileOutputStream(dataDir + "inbox.mbox");
		try {
			MboxrdStorageWriter writer = new MboxrdStorageWriter(writeStream, false);
			try {
				MailMessage msg = MailMessage.load(dataDir + "Message.msg");
				String[] fromMarker = { null };
				writer.writeMessage(msg, fromMarker);
				System.out.println(fromMarker[0]);
			} finally {
				if (writer != null)
					((IDisposable) writer).dispose();
			}
		} finally {
			if (writeStream != null)
				writeStream.close();
		}

It is requested to test with Aspose.Email for Java 18.11 and share your feedback with us.
