In Big Sur the mail client doesn't show a folder combining archives of all accounts. I'd like to have such a folder and tried creating a smart mailbox for this purpose as I'd successfully done to create an All Junk folder.
Here's the smart mailbox configuration that I thought would work:
However, it throws this error:
Any tips on how I can access an archive across accounts?
The problem indeed was with synchronisation: my iMac had this account configured as name@company.com, while MBA had this account configure as name.alias@company.com. Once I have deleted all IMAP accounts from both iMac and MBA and created it once again, problem disappeared.
Mail does have an action called "Archive" in the Message menu that moves the current message in to a directory called "Archive." I use it all day every day on my work IMAP account just like in Gmail. I stash everything in there and just rely on search to find what I need. It works great.
I don't think there's a way to remap the Delete key to perform an Archive action instead, but Archive does have a keyboard shortcut: control-command-A. If you find that as clunky as I do, you can remap it in System Preferences' Keyboard pane.
You can also add Archive to your toolbar if that's more your thing.

With the Mailboxes column showing click the plus sign to the right of the header "Favourites", which appears when hovering the pointer over it.
Then, in the resulting window, select "All Archive" as the Mailbox to add:
