First, I appreciate your desire to keep the forum clear of unneeded posts. So many post and leave their questions without closure. You can find links to all your posts by clicking your profile in upper right of screen.

Should you desire to stay with Thunderbird, here are tips to resolve threading: You need View>sort by>unthreaded. More info: In config editor, you can change default that applies to NEW folders you set up: mailnews.default_view_flags 0=unthreaded

To set many folders, follow these steps:

   In the header view, in the column header on the far right, open the options menu.
   At the very bottom is the option:
   -> "Apply current view to..."
   -> "Folder and its children..."
   -> Hover over an account
   -> In the next menu don't select a folder. Instead select the account name itself.

Sorry fell at the first fence. All I get in headers is all or normal

I'm referring to the message view pane, the right-most icon in the header (to the right of subject, from, etc) is a drop-down menu that has the options I mentioned. It's a bit tricky, I admit.

Bless you for this.

I hate automatic threads and you showed me how to restore a useable presentation without clicking all the time through three menu items.

BUT... the results of a search displayed as a list are still threaded, it's liveable, but if you have another great fix for that I'd be eternally grateful.
