I work for a charity who installed a Cisco system approximately 10 years ago. I have been administrating the back end of the system using the Cisco Unity Express Manager - i know that this is no longer supported by Cisco. My question, after moving to Windows 10 and not being able to roll back Internet Explorer to Version 5, how do i continue to add and delete users. If i dont use IE5 i cannot see all of the menus and can only pick a handful of users to assign phones to. How do i continue to do this?
