Here are some of the other Windows
Phone 7 features Microsoft is promoting as of interest to business
users:

Integration of the forthcoming Office Hub with Exchange Server and
SharePoint Server 2010. When Windows Phone 7 devices ship this holiday
season, they’ll be able to sync with Exchange Server 2007, Exchange Server 2010
and the current version of Exchange Online (that is based on Exchange 2007).
After that (no dates yet), Microsoft will enable syncing of the phones with
2010-enabled versions of Exchange Online and SharePoint Online. (Microsoft
showed offline syncing of the SharePoint client that is on the phones during the
morning keynote today). The secure connection is provided by Forefront Unified
Access Gateway (UAG).

Microsoft is planning to add secure connectivity for other BPOS
apps, including Communications Online, at some point. No dates for that
yet. On the CRM front, Microsoft is going to allow developers who’ve created
front-end client apps that connect to Dynamics CRM on the back end to offer
their wares via the Marketplace. But Microsoft itself isn’t going to be
providing a Windows Phone 7 version of its CRM product.

There will be no IPSEC virtual private networking available for
Windows Phone 7 devices. (This was available for Windows Mobile 6.x
phones). Microsoft is providing, however, passwords, PINs, remote wipe, factory
resettable settings and other security measures on top of the UAG connectivity,
giving users an extra layer of secure connectivity, officials said.

Windows Phone Marketplace remains the one and only place where
certified Windows Phone 7 apps will be available. But Microsoft will be
providing a secure subsection of the Marketplace to developers who want to make
beta versions of their apps available to a select group of testers. Microsoft is
still evaluating when/if/how it will allow enterprises to distribute versions of
their business applications to their own employees only; nothing new to say at
this point.

Microsoft isn’t changing its stance on requiring Windows Phone 7
applications to be written in managed code. If there are business
applications that developers are having problems getting to work without native
raw-socket access, Microsoft will work with those companies to try to find a
workaround, officials said.

At TechEd, Microsoft also released a set of new Windows Phone Marketplace
policies today. These include

Annual registration fee of $99
No limit to the number of paid apps
submitted
5 free apps per registration, $19.99 each
Free registration to
DreamSpark students
A new optional push notification service for third-party
developers
A new optional Trial API, for developers who want to create
try-then-buy apps
The ability to publish to all available Marketplace markets
though a new “worldwide distribution” option
Support for free, paid, freemium
(free with a paid upgrade path) and ad-funded models
