Do this while on your Inbox and using Table View. First, change the view to Unthreaded:

- make sure the Thread column is removed

- r. click any Message list column header (From, Subject, etc.) > click 'Apply current view to...' > 'Folder and its children...'

- navigate back to the top level (Account name) and click it

This is one of the worst designs I have seen in quite a while...

Give me a global setting. I know the developers decided that threading was cool, and if you agree great. But I have been using email since the 1980s, and I don't want it to change. Yes, I'm that old - older than Google. Older than the Internet.

It wasn't broken, but someone decided to "fix" it. Fine. You do you

Global settings for threading are in Settings > Appearance and can be applied to both existing and future folders.

I updated (or made sure it was set to my liking) that when I installed Thunderbird last week (this is a new PC.)

It had NO impact on the sent folder.

Try again.

Giving me a "global setting" that doesn't impact the existing folders (because the individual folders have their own settings is NOT a GLOBAL setting. It is a "desire for future folders."

As I said, global settings for threading are in Settings > Appearance and can be applied to both existing and future folders. I did not just make that up.

Do you see more settings below those in your screen image? "Propagate threading and sorting settings to:" See my screen image. If you have a recent version of Thunderbird, they are there.

The sent folder may have been created before you had a chance to set these settings because Thunderbird makes users set up an account before anything else.

I will not try again. I'm not going to offer more of my time to such an angry and argumentative person.

Obviously I did NOT see that.

And so I will go back to my original statement.

This is a bad design

I think you are missing the point = i have already changed this to no threading as i said when i started this. This issue isn't that threading is still on in any account. The issue is, when threading is off the threading column remains and i must remove it for every folder i have. One would reasonably think that if threading was turned off, it would also remove that column globally.
