Probably not. I'm not an expert on these particular protocols, but the authors of leafnode appear to agree with me. Exchange appears to implement a proprietary protocol for this authentication. There do appear to be ways to configure outlook to use SASL or encrypted tunnels, so there *are* standards-based ways of getting this sort of authentication. You also get the benefit of the higher level of confidence in the security of an open protocol and implementation. Authenticating Outlook clients sounds like something in the way of closing the barn door after the horse is gone, anyway.
