we have Unity 5.x with Exchange. It's possible to make users NOT ABLE to change their notification settings using the phones, but leaving this chance using Personal Call Assistant?
Many thanks in advance,
In Unity 5.0 you can do this using a custom key map - Open the Custom Key Map utility, pick one of the 3 customizations and on the "setup" tab you can exclude access to the Message Notification menu entirely.
You can use the "reset key mappings" option to start with the subscribers' current conversation selection and modify only this to ensure a smooth transition. Then just assign the users you want to have this restriction to that conversation and you're good to go.
