    Hi Pluppo, is it possible for you to use the IE Developer Tools' (F12) network facility or an application like Fiddler or HTTPWatch to identify the resource that responds with the 401 status after you have logged in? My guess is that it's ECP, since that's most closely related to OWA. On the Client Access servers, do you have OWA and ECP authentication types both set to forms-based for all servers?

     

    thanks

Hi Cody,

 

Thanks for your reply. I just tried disabling strict updated on the iApp, and then removing the OneConnect profile from the VIP, but unfortunately the symptoms are still the same. I am still getting a second "Window Security" authentication prompt after logging in to the OWA form.
