Buen día.

 

Comparto el enlace en el que se describe el fallo que estamos presentando:

 

https://support.microsoft.com/en-us/office/classic-outlook-pop-account-profiles-hang-and-freeze-after-windows-11-update-to-kb5074109-590fe356-ecc2-49f4-b9e3-bd39fafa58f6.

 

Solicito que este caso sea escalado con urgencia al equipo de Microsoft Windows para su revisión y corrección, ya que está generando múltiples fallos.

               

Adicionalmente, comparto un segundo enlace en el que se evidencia la cantidad de usuarios afectados, con el fin de que este incidente sea tratado con prioridad:

 

Outlook Classic not opening properly or recording sent mails after 2026-01 Security Update (KB5074109) (26200.7623) - Microsoft Q&A

 

Necesitamos una solución alternativa para los equipos en los que no es posible desinstalar la actualización KB5074109, debido a que el propio Windows impide revertirla. Esto agrava el impacto y dificulta la mitigación temporal del problema.

 

Agradezco su pronta gestión.

 

Atentamente,

    No me da la opción de hacer eso. Cuando entro a ese apartado, la actualización no aparece, y cuando reviso el historial, ya figura instalada la actualización KB5074109.
