AADSTS50194: la aplicación no está configurada como aplicación tenant múltiple

Incidencia

When using Microsoft 365 activities, you encounter the following error: "AADSTS50194: Application <appID> is not configured as a multitenant application. Usage of the /common endpoint is not supported for such applications created after 10/15/2018. Use a tenant-specific endpoint or configure the application to be multitenant."

Solución

Apply either one of the following recommendations:

• Set a value for the Tenant parameter of the Microsoft365 activity from UiPath.

• If you don't want to provide multitenant access, configure the app as single tenant, but provide the Tenant ID in Microsoft 365 Scope.

Nota:

• If a token is not present, it is required to authenticate all the time, and time will be lost during the automation. Delete the cache from its storage location. For more information on that, follow this article: How To Manage The Authentication Tokens Generated By Microsoft Office 365 Activities.
• The token comes with an expiration date. Deleting the cache does not invalidate the token. To change the token cache policy, do that in Azure by changing the expiration time.
