I have set up a new account with IMAP protocol, and configured archiving this way:

Account settings -> myaccount@new.server
                 -> Copies & Folders
                 -> Messages Archives
                 [x] Keep messages archives in
                     [x] "Archives" folder on: -> Local Folders

(I have also tried

                 [x] Keep messages archives in
                     [x] Other: -> "Archives" on Local Folders


But it does not work. When I..

  • pick an e-mail in myaccount@new.server/Inbox folder
  • right click -> archive

I expect that:

  • the e-mail is moved to Local Folders/Archives/2020/2020-01
  • the e-mail is no longer in myaccount@new.server/Inbox

But instead:

  • new (unwanted) folders myaccount@new.server/Archives/2020/2020-01 are created (both locally and distantly)
  • the e-mail is moved to these new folders instead (both locally and distantly)
  • the e-mail is not even locally copied in Local Folders/Archives

The problem persists after I compact folders and restart Thunderbird.

What could be wrong?
How to fix this behaviour?
Is the problem rather related to Thunderbird or to new.server IMAP configuration?
How to investigate?

Okay, got it. Just make sure that you also do the same parametrization for every identity associated to your account@new.server:

Account settings -> myaccount@new.server
                 -> Manage Identities...
                 -> <pick one, and repeat for each>
                     -> Edit...
                     -> Copies & Folders
                     -> Messages archives
                     [x] Keep messages archives in
                         [x] "Archives" folder on: -> Local Folders
