failed.pst.zip (343.1 KB)

if operation is executed for single file, issue can not be reproduced, you need to execute current operation for a data list and have a large file size.

File file = new File("file_failed.pst");
	try (PersonalStorage storage = PersonalStorage.create(file.getAbsolutePath(), 0)) {
		FolderInfo folder = storage.getRootFolder().addSubFolder("Test folder");

		InputStream stream = new FileInputStream("failed.pst");

		MailMessage mailMessage = MailMessage.load(stream);
		mailMessage.setSubject("test subject");
		MapiMessage mapiMessage = MapiMessage.fromMailMessage(mailMessage, MapiConversionOptions.getUnicodeFormat());
		folder.addMessage(mapiMessage);
		mailMessage.dispose();
		mapiMessage.dispose();
	}

We have tested the scenario using the latest version of Aspose.Email for Java 22.5 and have not found the shared issue. So, please use Aspose.Email for Java 22.5.
