I am running Windows 8 and Outlook 2010. I have created a profile for my company's Exchange Server. The set-up is correct because my username is recognized. However when I try to access Outlook, I get asked for my credentials by "Windows Security." It has the dots in the dialogue box indicating that there is a saved password. Unfortunately, I have no idea what that old password is and where it is coming from. When I try to overwrite it with the new and correct password and check the remember my password box, it just ignores it and redisplays the security message with the old password pre-filled. I am dead in the water with my corporate email which I don't need to add is not good. I have deleted anything that might be an Outlook credential using the Control Panel. I have deleted my profile and started from scratch. I have also deleted my personal MSN account email and tried that but with the same results. I have read everything that I can find that might offer a viable suggestion. There are some that suggest that the password is stored in the registry, but I know from experience not to mess with the registry without some professional advice, especially with a new operating system. Ideas?
