Microsoft’s latest version of Skype now supports the OneDrive extension. The add-in allows users to share files stored in their OneDrive cloud storage. The feature was first introduced in the Skype Insider Preview 8.35.76.30 build on November 20, 2018. It is now available in the Store app for Windows 10 PC, iPhone, iPad, Android, Windows/Mac desktop apps and Linux Web. The shared files will open in the app if the receiver has it installed on his mobile device, otherwise, the app will provide a preview of the shared document.
