You have an Exchange Server 2016 environment that has parent and child domains.
Exchange Server is installed in the root domain.
A user in a child domain logs in to Outlook Web Access (OWA).
In this scenario when the user accesses OWA Voice mail options (OWA -> Options -> General -> Voice mail -> Notifications), they receive the following error message:

Play on Phone
Voice Mail Preview
