Currently I'm working on a task to fix the process of opening custom web page in outlook client from custom ribbon button, it's similar to this question: JavaScript pop-up in Dynamics CRM 2011 Outlook client client
However, I have configured the website to have the same authentication token from the same ADFS as CRM web. If I open it using IE/any other web browsers (in UR 12), it works fine. If I open it using outlook client, it keep prompting the user to authenticate (which is quite annoying for some users).
I've read these, but they are only applicable for CRM form, not custom web app: ADFS (CRM 2011) - Authentication Issue in Microsoft Outlook Client for CRM (Response.Redirect(...) & Window.Open(...)) http://msdn.microsoft.com/en-us/library/jj602956.aspx
Anyone have any idea on this? FYI, I'm using CRM 2011 UR 12, and Outlook 2010 with CRM client.
TIA
