I have this problem with Exchange 2016. Outlook 2016 clients prompt for password upon launch. Most prevalent after a reboot or signing out/in to Windows. Prior versions of outlook (2013 and 2010) do not do this in testing. It's only 2016. This is impacting our deployment plans for Office 2016.... as in we're not! 153554b96e
