Big Sur - Mail - Where is my common bin ?

Hi, I did the suggestion above but it still shows me mail boxes for each email I use separate like this. This was previously not the case. I can I remove it being displayed under favourites combined and for each email address separate like this?

aussiemediaguy, 

Got it, you mean the trash/deleted folder, we apologize for missing that.

Please do this:

To the right of Favorites in the side bar click the plus sign. You'll see a field that says, 'Mailbox to Add', in there choose All Trash then click OK. Now under Favorites you'll see an option for All Trash which, when clicked on, will show a combination of all messages that are in the separate trash folders in your Mail app. There will also be an arrow to the left of All Trash that you can use to see each account's folder individually if you prefer.

Thanks.

Good day to you aussiemediaguy, 

It sounds to us like you’re looking for a listing for All Inboxes that typically appears under the Favorites heading in the Mail app. Do we have that right? Even though each email account would still have their own inbox, all messages would appear together in one place. 

If so, this article in the macOS Mail User Guide can help get that all set up: Use favorite mailboxes in Mail on Mac

Thanks. 

Here's a screen recording of what AnnieL2 is referring to except I'm adding All Junk instead of All Trash:

If you followed those instructions you should have gotten this:
