When sending a document for parallel review, the contract administrator can send agreement documents for both internal and external reviews using Office 365 from CLM. When a document is sent for external review, the reviewers receive an email link containing a SharePoint link of the document. The reviewer can open the document online, edit it and inform the contract administrator after he ends the review. For more information about the external review, see Sending an Agreement Document for Collaborative Review using Office 365 Review
