Actually make that:

function MailInbox:OnMailRemoved(mailId)
    if self.control:IsHidden() then
        if AreId64sEqual(mailId, self.dirtyMail) then
            self.dirtyMail = nil
        end

        if AreId64sEqual(mailId, self.mailId) then
            self.mailId = nil
        end
    end

    self.reportedMailIds[zo_getSafeId64Key(mailId)] = nil
    self:RefreshData()
end
