Can you manually thread emails in Thunderbird?

more options

Hi, I've been experiencing a problem with Thunderbird recently where replies to my messages sometimes won't be added to that conversation's thread despite being in the Re: Subject format. Is there any way to manually add these emails to the thread? I'm on version 128.4.2esr and use Thunderbird with Windows 10.

Have you set the folder to View>sort by>Threading ? That would be my first check.

If you mean, while in Threaded view, can you move a message to a new parent thread, you cannot in Thunderbird. However, Betterbird has a feature to rethread messages. See the Rethreading section here.

Yes, I've also tried repairing the folders the messages are in as well as moving them back and forth from my inbox. Could the issues possibly be from their length? The affected emails are all >5000 characters each.
