Configure the number of input failures before Outlook Voice Access users are disconnected in Exchange Server
Applies to: Exchange Server 2013, Exchange Server 2016
You can configure the number of times that users who call in to an Outlook Voice Access number can enter incorrect data before they're disconnected. This setting applies to both Outlook Voice Access users and unauthenticated callers who use directory search.
The following are examples of types of data that are considered incorrect:
A caller requests an extension number that isn't found in the system.
The system can't locate the user's extension number to transfer the call.
A caller presses a menu option that isn't valid.
The value of this setting can be from 1 through 20. For most organizations, this value should be set to the default of three attempts. Setting this value too low may prematurely disconnect callers.
