If you enjoy using some Facebook features in apps like OneDrive , People and others in Windows 8.1 and Windows Phone, it looks like they won't be available anymore. A new support page shows that, because of a change in the Graph API, Facebook Connect features are no longer available for those apps, along with other services from Microsoft.

Here's what Microsoft has to say:

"Facebook's Graph API is the tool that we use to connect your Microsoft account to Facebook. It brings contact information from your Facebook friends into Outlook.com and the Windows People app, keeps those contacts up-to-date, and provides options in apps and services like Photo Gallery, Movie Maker, and OneDrive.com to share to Facebook. We collectively refer to these features as Facebook Connect. Due to these changes, Facebook Connect features will no longer be supported."

The support page goes into more detail on what specific apps and services will be affected by this change. Here's the list of apps that will no longer support Facebook Connects features:

Outlook.com Contacts

Outlook.com, Windows, Windows Phone and Office 365 Calendar sync
