Azure Active Directory B2B collaboration helps improve security while simplifying the management of partner access to resources, including SaaS apps such as Office 365, Salesforce, many Azure services, and other mobile, cloud, and on-premises claims-aware applications. An email-verified process allows partners of all sizes, with or without an existing Azure AD subscription, to manage their accounts and get access to the line-of-business applications you provide.
B2B collaboration is included with all Azure AD editions. For more information, please visit the
Azure Active Directory B2B collaboration documentation webpage.
