Recently I came across the stage to support collaboration between internal and external users in Office 365 environment. Basically we are talking about an extranet scenario where you need to allow a group of employees of an organization to work with different people outside the organization, are you familiar?
It is well known that SharePoint 2010 supports functionality features to attack extranet scenarios including authentication. As it happens, Microsoft Office 365 already configured authentication provider of Windows Live with which we can make users with Microsoft Windows Live account to access our SharePoint portal without us having to provision, manage, or maintain access credentials.
Some companies create active directory accounts for customers or suppliers and also ask SharePoint developers to develop webparts to allow the external user to change the domain account directly from the extra net portal. Personally I think that exposing the AD for an external update your data via a programming interface is not for me.
In this video I show how SharePoint 2010 Online Office 365 makes setting Extranet scenario by supporting authentication with Windows Live. Of course, thanks for watching this video and do not forget to subscribe.
