Microsoft has been quite explicit on the matter: Windows Phone 7 Series is being designed first and foremost for the consumer market. The result is the emphasis on a strong, consistent, effective user interface, possibly at the expense of functionality; Microsoft wants to have this thing out in time for the "holiday season" this year, so there's a limited window for further development, at least for the initial release.

That said, the phone does have features aimed at the enterprise market. Obviously, there's Exchange support, with ActiveSync, providing push mail, address book sync, and all those features that we know and love. In common with Outlook 2010, Windows Phone 7 Series also seems to support multiple Exchange servers concurrently. I say "seems" because it didn't quite work when we tried, but that seemed to be due to a bad password rather than any fundamental flaw—the phone was happy to accept the configuration and created two distinct Outlook Tiles on the Start page, so it looked like it was doing the right thing.
