Only on-premises account enabled for implicit sign-in

Configures this policy to decide whether only on-premises accounts are enabled for implicit sign in. If you enable this policy, only on-premises accounts are enabled for implicit sign in. Microsoft Edge doesn't attempt to implicitly sign in to Microsoft Services account (MSA) or Azure Active Directory (AAD) accounts. Upgrade from on-premises accounts to AAD accounts are also stopped. If you disable or don't configure this policy, all accounts are enabled for implicit sign in. This policy only takes effect when policy 'ConfigureOnPremisesAccountAutoSignIn' (Configure automatic sign in with an Active Directory domain account when there is no Azure AD domain account) is enabled and is set to 'SignInAndMakeDomainAccountNonRemovable'.
