I have installed Cognos MS office 10.2.1 and able to configure to view the report. But when i keep the mouse over the report and right click over the report it is asking credentials. I have choosen SSO and windows authentication enabled. so it should not pop up for credentials. Also if i cancel and import content, reports are imported in to MS office. if again i keep the mouse over credentials screen pops up. How to stop this pop up. refer Attached screenshot.
