4.9 CAS_OABAvailability

Use this Knowledge Script to monitor the availability of offline address books (OABs) for a Client Access server. This script raises an event if OABs cannot be downloaded.

This Knowledge Script monitors the offline address books only if they are hosted in a virtual directory. If they are in a public folder, this Knowledge Script does not monitor those.

NOTE: This script is currently not supported for use with Exchange Server 2013, 2016, and 2019.

Set the following parameters as needed:

Parameter	How to Set It
General Settings
Communicate only with Exchange Servers in the local domain?	Select Yes to test only Exchange Servers in the same domain as the server on which you run the CAS_OABAvailability job. When this option is unselected, certain tests for the Client Access server attempt to contact all Mailbox servers in your organization. These tests will fail if the Exchange accounts in one domain do not have access to other domains. Leave this option unselected if you specify a Mailbox server in the Mailbox server hosting offline address books to be accessed parameter.
Ignore these Mailbox servers when testing CAS to MBS communications	Provide a comma-separated list of the host names of the Mailbox servers that you want to exclude from availability testing between the Client Access server and the Mailbox server. Leave this option blank if you specify a Mailbox server in the Mailbox server hosting offline address books to be accessed parameter.
Mailbox server hosting offline address books to be accessed	By default, the OABAvailability job tests connectivity to all Mailbox servers. Use this parameter to enable testing to one Mailbox server. Enter the hostname of the Mailbox server computer that hosts the OABs you want to monitor. The hostname need not be fully qualified unless DNS lookup does not resolve the simple name.
Job failure event notification
Event severity when job fails	Set the severity level, from 1 to 40, to indicate the importance of an event in which the OABAvailability job fails. The default is 5.
Monitor Offline Address Book Availability
