Sort mailboxes in Mail alphabetically. How?

1. Close the macOS Mail app, if it is currently open.
2. Launch Finder app. While pressing the option key on your keyboard, click onto the ‘Go‘ menu and then select ‘Library‘.
3. Scroll down till you find the ‘Mail‘ folder and open the folder.
4. Within the Mail folder, you will find one or more subfolders named like V1 / V2 / V3 …., in my case it is named ‘V6’.
5. Trash all ‘Vx’-folders. Note: Do not finally delete them until you are sure you will not need them anymore.
6. Launch macOS Mail app. All email accounts will be synced again. This can take a while. After the sync is complete, all of your mailbox folders are shown again in alphabetical order.

How can I sort my mailboxes in Mail alphabetically. Have Catalina 10.15.7 on MacBook pro

Drag them into alphabetical order.

Trash all ‘Vx’-folders. Note:1.  Do not finally delete them until you are sure you will not need them anymore.

That will be rather disastrous if you have POP email accounts or store email messages in folders "On My Mac."

I agree with glsp.

Thank you to Steve and others for their solutions. Unfortunately these solutions are not feasible for the majority of Apple users, who either would not fully understand what to do, or who might make an error and cause severe problems for their system.

Issues that are likely to affect many users should be provided as a feature using standard simple Apple interfaces, such as

Order Mailbox -> Alphabetically, By Date of Creation, etc.

I agree. I'm going to send Apple feedback to have automatic folder sorting as selectable feature, or at least add a "sort Alphabetically" as a menu option that you can apply manually. I've gotten used to those being the standard 2 options in most mainstream applications.

I thought you were joking at first,, surly there must be a way other than "Manual sorting" and with out entering code in Terminal.

Tested on OS X 10.14 and 10.15.7

Thanks Steve, that worked for me. The first time and now again a week later, hopefully this bug is fixed soon so I don't have to keep doing it.

This has been a bug for two decades. Apple just doesn't care.

Thank you. That was a very helpful response. The issue was driving me nuts!

Agreed!! Please proceed with caution. Do it only if you know what you're doing

this works for me too, thanks Steve D 21

That worked. Thank you!

Worked for me! Thanks, Steve :)
