Add a trash and junk folder

SpamSieve

I have four accounts running SpamSieve and one of them, an Outlook account does not have a Trash or a Junk folder.
I am using Apple Mail. The other three accounts are fine. Is there a way for me to add this to Apple Mail?

Yes, you can create a Trash or Junk mailbox in Apple Mail and then go to Preferences ‣ Accounts ‣ Mailbox Behaviors to designate those mailboxes as the special Trash and Junk mailboxes.

(It doesn’t matter to SpamSieve whether you have such mailboxes or not.)
