In Exchange 2010, we started using unified messaging and set up Auto Attendants. We setup a admin role/RBAC for people of a security group to be able to update the message on the auto attendants. They have the UMPrompts assigned role. All of this is working great in 2010. We have now migrated to 2013, and the users who were migrated from 2010 to 2013 can no longer update the messages through TUI. Newly created 2013 users can and are assigned the EXASCT same permission as the users who have been doing this for well over a year on 2010. When they call the AA and press #,* they are asked to provide their extension, after doing so the system tells them that extension is not correct. and asks for the extension again. Newly created users with the same permissions get prompted for their PIN and can log in and change the message just fine.
Confirmed Bug? anybody else having this issue?
What would be different for this process between a user who was migrated from a previous version like 2010 compared to a newer user who has only ever existed on 2013?
