The manual approach can work fine if you only have a few emails. But it has some limits and can get difficult for bigger setups. For large or business use, it may not be the best option. That&rsquo;s why many people prefer using the <strong>MailConverterTools IMAP Migration Tool<\/strong> instead. It can move multiple emails at once and keeps things more organized.
