Sidebar not showing all IMAP folders

[Felix Finch]

I use mutt to connect to Lookout / office365, and teh sidebar only shows two mail folders, INBOX and "All Mail".  From somewhere lost in time, I added these two lines to my .muttrc:

    mailboxes +INBOX "+All Mail" "Deleted Items" Notes "Junk Email" Trash
    sidebar_whitelist =INBOX "=All Mail" "=Deleted Items" =Notes "=Junk Email" =Trash

I can switch to these folders and more by name, but the sidebar never shows any more than INBOX and All Mail.  The documentation says

    This command specifies mailboxes that will always be displayed in the sidebar, even if $sidebar_new_mail_only is set and the mailbox does not contain new mail.
