Problem
Recently, a customer has created a new SharePoint environment and added an alternate access mapping (AAM) with the URL containing a “_” character (ex: http://intranet_QA). When opening an InfoPath form in an IE browser (from IE8 up to IE11), the following error was being throwned:
“The form cannot be displayed in the browser because the use of session cookies has been disabled in the current browser settings. In order to load the form, session cookies must be allowed.”
In other browsers, the InfoPath form opened successfully, without throwing any error.
Cause
This behavior is due to the fact that Internet Explorer doesn’t accept cookies with host names that contain the “_” character.
Solution
To solve this problem, the “_” character was removed from the URL. In this example:
- http://intranet_QA – doesn’t work
- http://intranetQA – works
Hope this helps!
