When a user attempts to click on attach file nothing happens. when I move users account to another OU the attachment function works fine. My guess is that this is a GPO causing the issue but both OUs have the same GPOs except for a folder redirection GPO. Also if the same users click File and then click Open they receive the following message &quot;Infopath had encountered an error. The operation failed&quot;. Any ideas as to what is preventing Infopath from calling Windows Explorer for an entire OU?<br /></p>
