Validation differences by supported account types (signInAudience)

When registering an application with the Microsoft identity platform for developers, you're asked to select which account types your application supports. You can refer to the Help me choose link under Supported account types during the registration process. The value you select for this property has implications on other app object properties.

After the application has been registered, you can check or change the account type that the application supports at any time. Under the Manage pane of your application, search for Manifest and find the signInAudience value. The different account types, and the corresponding signInAudience are shown in the following table:

Supported account types (Register an application) signInAudience (Manifest)
Accounts in this organizational directory only (Single tenant) AzureADMyOrg
Accounts in any organizational directory (Any Microsoft Entra directory - Multitenant) AzureADMultipleOrgs

If you change this property you may need to change other properties first.
