Document link previewing and permissioning while composing an email

摘要

Enhanced links in a message composition surface are described. A uniform resource locator (URL) may be identified while a user is composing a message in a message composition surface of an electronic message such as an email. A source of the URL and the file type of the document linked to by the URL can be determined and a preview of the document can be rendered in the message composition surface. When the source is a cloud storage location, access permissions for the document can be adjusted from within email—without the user navigating to a file management site of the cloud storage. When the file type is a productivity application, a link rendering element can call a productivity application service to provide interaction functionality for the productivity application file and facilitate the rendering of the productivity application file.
