​Our first update to SharePoint Online (SPO) since the launch of Office 365 (O365) became generally available on June 28, 2011 is now complete worldwide. We thought it would be a good time to share information about the new features and fixes available as part of this service update. On a broad level, this update enables greater reach to both people and external data, while at the same time increasing the number of supported devices and Web browsers. We also added some self-management recovery capabilities. But there’s a lot more, too.

Business Connectivity ServicesAt SharePoint Conference 2011 (Oct. 3-6) in Anaheim, CA, Jeff Teper (Corporate Vice President of SharePoint engineering) announced, “Business Connectivity Services (BCS) is coming to SharePoint Online by the end of this calendar year.” Available now to all Office 365 midsize and enterprise customers worldwide, BCS in SPO enables them to connect to external data sources via Windows Communication Foundation (WCF) Web Services endpoints in both read and write modes.

Now, you can design solutions that extend collaboration capabilities that include external business data, such as line-of-business (LoB) applications that sit behind customer firewalls, or are being transitioned to the cloud (think SQL Azure). Best yet, you can download SharePoint Designer 2010 for free to help make the connections.

BCS is all about breaking down the boundaries to external data. Now let’s turn to breaking down the barriers when you work with people. This service update adds support for working with people who are not part of your company, such as vendors, trusted business partners, and customers. With these external sharing capabilities, a company can invite external users to view, share, and collaborate on their SharePoint Online sites. This feature is turned off by default, but a SharePoint Online Administrator can enable external sharing for the whole company. Then, individual site collection owner administrators can decide if they wish to share externally.

• Companies using SharePoint Online for small businesses will no longer be able to delete their root site—a   great benefit considering that this offering is based around a single site collection.
• SharePoint Online-based Public Websites will no longer prompt unauthenticated users for credentials on their mobile devices.
• When Windows Phone 7.5, codenamed “Mango” was released, customers that applied a vanity URL to their Office 365 tenancy could not connect to their SharePoint Online site via the “Locations” section of the Office Hub. Now they can.
• The “-my” root site collection—the parent site collection to all of a tenant’s My Sites—has returned to the SharePoint Online Administration Center within the list of site collections. It is again possible to allocate server resources, assign owners, and now this site collection cannot be deleted.
