I'd like to get a better sense that the Exchange folks and the SharePoint folks have been talking to each other. The email integration in MOSS 2007 is sorely lacking .. very much so.
I would not push for reversing the decision to phase out Exchange public folders .. I actually think they have outlived their usefulness. But for companies that have dependencies on their functionality, can we expect SharePoint to be able to pick this up with more solid integration in the future? And not just the ability to send email to a document library, or a migration tool, but allowing posts/emails to be directed to SharePoint in a scaleable way, and be accessible in a user-friendly way. Think "public folder web part".
