I have created an InfoPath form for one of the my clients. The site is SharePoint online site. When I created that form it was publishing successfully. But since few days the InfoPath asks for the credentials repeatedly when I try to publish the form on that particular site. When I publish the same form to the another SharePoint online site then it gets done successfully. I have attached the screenshot attached with this post. Observing the popup which appears to enter the credentials, seems to be of SharePoint On Premise where as the site is of SharePoint online. We logged the support call to Microsoft but they told that the site is configured for the SSO. But the site can be opened and I can login from the non organization PC also the site is not configured for SSO. What could be the resolution for this? Can anyone please help me?
