A virus will target any email reader. That's not the problem as it targets a OS, not really a particular app which has numerous versions. The prolem with Outlook is that it is a door wide open to critical business apps and databases and all Office documents, and it offers automation that enables it access to a whole system, something that Outlook Express does not implement.
Of course there are security issues associated to the HTML component, but it is the same as Internet Explorer and also used in Outlook. The fact that you use Outlook instead of OE will not give you more or less protection for this common component.
So the security of OE mostly depends on the security of Internet Explorer, but the security of Outlook also depends on the security of Office and automation components that have a high business value, that's why I think it should not be used for Internet emails. In OE, the risk is mostly limited to the data of one user on one host, but hardly extends to a whole system.
I don't say the Outlook is unneeded, just that it should be used separately only for internal enterprise applications or personal productivity, simultaneously with OE. Managing Internet emails in Outlook is too dangerous. This is a common security advice: separate usages and do not expose in the same application private data and potentially dangerous and unsecured Internet data. OE allows to improve such separation even for Outlook users.
