unable to see import mailbox -OS Catalina
I've used Mac Mail to import mailboxes I had backed up on a disc. When i import mail it tells me that the mailbox's have been added to the 'import' mailbox. However I am unable to find any Import mailbox anywhere in Mail.
I've tried closing and spending Mail, restarting my Mac but still the Import Mailbox does not appear in Mail.
Can anyone help please
