Same question as the OP. Legacy ActiveSync on the Kyocera Dura's was great, but with basic auth deprecated, its gone. It's also worth noting that the deprecation of basic authentication will also prevent the use of app passwords with apps that don't support 2FA (such as the legacy ActiveSync Protocol). There is an Urgent need for a solution. Maybe Outlook, or [Login to see the link] on the Qin-F30?
