“There was a problem loading your options” error when a user accesses OWA Voice Mail options in Exchange Server 2016

Consider the following scenario:

• 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:

Note This error occurs for the following options:

• Notifications

• Greetings

• Outlook Voice Access

• Play on Phone

• Voice Mail Preview

This issue happens because the ViewEntireForest parameter is not set to True when some Unified Messaging cmdlets are initialized.
