I am doing a 365 deployment for a company and some of the users previously had office 2007 and some had office 2013. The issue I am running into deals with the people that had office 2007. I use the Microsoft Fix It tool to uninstall Office 2007. After the computer restarts, I install Office 365 ProPlus from OWA for each individual user. When setting up these people's Outlook profiles, it always hangs up on the Windows Security Credentials asking for the exchange password again. I have to open task manager and close out Outlook. There are no issues with the users who had 2013 installed on their computers. Does anyone have a solution to this problem?
