Windows Phone 7 is a great productivity tool because it includes Office Mobile. SharePoint Workspace Mobile is part of Office Mobile and allows users to download and synchronize Office documents with SharePoint servers, whether they reside on-premises or in the cloud.
For more information about SharePoint Workspace Mobile, see the article “Use Microsoft SharePoint Workspace Mobile” on Microsoft.com.
SharePoint Workspace Mobile on Windows Phone supports SharePoint Server 2010 or SharePoint Foundation 2010, and is also compatible with SharePoint Online in Microsoft Office 365. SharePoint Workspace Mobile cannot connect to sites that are on earlier versions of SharePoint.
Additional information about configuring SharePoint sites for external access is available in “Configure external access for mobile devices (SharePoint Server 2010)” on Microsoft TechNet.
A virtual private network (VPN) connection is required to enable access users to connect to internal SharePoint sites from outside the firewall . The only VPN server that is supported by Windows Phone 7 is the Microsoft Forefront Unified Access Gateway (UAG). Forefront UAG with Service Pack 1 (SP1) is recommended. For more information about Forefront UAG Sharepoint Publishing, see the “SharePoint Publishing Guide” and “Publishing SharePoint sites for SharePoint Workspace Mobile.”
Keep an eye on the SharePoint team blog for updates to resources on how to connect Windows Phone 7 with SharePoint sites.
