What is Azure AD B2B?

Azure AD B2B (Business to Business) collaboration enables you to securely share your organization's applications and resources with external users (guests) from other organizations, such as partners, vendors, and suppliers. It allows external users to access your resources using their own identities, eliminating the need to create and manage separate accounts for them in your Azure AD tenant. Common use cases include collaborating on documents, sharing applications, and allowing partners to access specific resources within your organization's environment.
