Hi,
We have developed one custom webpage and we have added one button on that page to open new contact form. it will work when we use any browser. but when we use this custom page from CRM outlook client and click on new contact button its asking for username and password. we already configure IFD mode . also it will not work on premise or out side premise. every time its redirect to login page. when we provide credentials its opening main page. any idea why its not working from Outlook client?
