Accessing Outlook on the web for business using organizational credentials.
Dear Usha K1,
Good day.
Active Directory Federation Services (ADFS) is a type of Federated Identity Management system that also provides Single Sign-on (SSO ) capabilities. It supports both SAML and OIDC. ADFS is primarily used to set up trust between ADDS and other systems such as Azure AD or other ADDS forests.
