Guest Access – Working with External Contributors in Project Central
Project success is dependent on many contributors, both internal and external to your organization. The latest release from Project Central allows users to invite any person from any Microsoft Azure Active Directory to collaborate in projects.
With this latest update, external project team members, contractors, or stakeholders can be added to individual or multiple projects without creating unique logins. They can simply be invited to collaborate using their existing Microsoft work account.
