On the Apple discussions forum, there are a number of threads about Mac Mail mailboxes disappearing. With situation like this, you can try re-indexing the mailboxes to do email recovery on Mac. A Mac veteran provided this method on the forum. Many users have tried it and successfully recovered hundreds of emails by re-indexing. As for how to re-index the mailboxes, you can following the instructions below.

1. From the menu bar on the top of Mac screen, select System Preferences > Spotlight.

2. In the Spotlight window, go to the Privacy tab. And then you can drag a folder or an entire volume (such as your hard drive) to the list. If prompted for confirmation, just click OK.

3. After selecting, you will go to another interface, you need to click the Privacy tab. And then you can drag a folder or an entire volume (such as your hard drive) to the list. If prompted for confirmation, just click OK.

4. Next, you should remove the item or volume you just added to the list, you need to click it and then click the minus ("-") button on the bottom. And close "Spotlight preferences". The Spotlight will re-index the contents of the folder or volume.

Hopefully this method can work. But there are some users to whom this method is not useful. They rebuilt the mailbox and still can't get the messages to appear. The re-indexing will not work if the Mail folders files don’t exist on the computer anymore. If it’s the case, it means t hat your Mail folder is lost and you need to use a different way to restore your Mail folder.

Method 4. Restore Mac Mail from Time Machine backup

Many Mac users back up their Macs with Time Machine. If you are one of them and you have lost Mail messages recently, you can restore Mail from Time Machine. An article on macissues.com provides three options to manually restore disappeared Mail folder from Time Machine.

4. Find the files with the name of the mailboxes that have disappeared. Restore them to desktop. Exit Time Machine.

5. Import the .mbox file into Apple Mail on your Mac. From the Import mailbox, drag the email messages into the mailbox you want them to go to.

Sometimes, restoring missing Mac Mail folders from Time Machine is just able to recover a few messages. This approach may simply not work in some cases. And if you want to restore your entire system to a prior backup, you need to guess what if something terrible happen and we need to give up one of the three.

You'd better have a mental preparation. What’s more, it is not an easy thing if you want to perform this process, although this article provides detailed steps for you, many users still don't know how to operate. If you are a Mac newbie, it's better not to attempt that.
