No matter what we try, we get the following error when attempting to set up an Outlook profile: Outlook 2013 works great in Windows 7, but we want to upgrade our development machines to Windows 10 and can't get Outlook 2013 to work. We've been using Windows 7 for years and have used Outlook 2007, 2010, 2012, and 2013 (which is currently being used). We have an isolated network used for test and development with its own Exchange server.
