DOCUMENT COLLABORATION

One or more techniques and/or systems provide for an entity to receive collaboration context data regarding activities that have taken place with respect to a document when the entity views a reference to the document comprised within a communication directed to the entity. For example, a hyperlink related to a document may be emailed to an entity when the document is shared with the entity. Subsequently, when the entity views the email comprising the hyperlink, the entity may be provided with contextual information regarding the document (e.g., entities that have viewed the document, edits other entities have made to the document, etc.). In one embodiment, such information may be presented to the entity in the same application (e.g., email client and/or email service) as the email. In this way, the entity may be provided with information that may help the entity assess whether to access a shared document, for example.
