Consistent sharing behavior for Office file types and custom file types
Make a sharing behavior the same for both Office files types and custom files types.
File Handlers 2.0 allow to register custom files types (that can be configured to open by custom web applications) for Office365 tenant.
When you share this custom file type, a person who receives sharing link will download the file when after clicking on the link. Instead of downloading, the file should have been opened in a custom web application that the file is configured to open.
For instance, for Office file types, when a person clicks on a shared Office file - it is opened in an Office app.
For both Office files types and custom files types, when clicking on a sharing link the file should be opened in the application that opens this file.
