Troubleshoot TA-Exchange-Mailbox

The TA-Exchange-Mailbox add-on should install on your Exchange Server hosts without problems as long as you configure it for the version of Exchange Server you run before you deploy it.

If you do not configure the add-on for your version of Exchange Server before you deploy it, then the add-on only collects data inputs that are common to all supported versions of Exchange Server. This results in missing data that is specific to your version of Exchange Server. See Configure TA-Exchange-Mailbox for the procedure to configure the add-on and distribute it to your Exchange Server hosts.

If you upgrade from an earlier version of the Splunk App for Microsoft Exchange, complete the upgrade instructions in the Splunk App for Microsoft Exchange manual to ensure that the add-on collects all Exchange Server data for the version of Exchange Server that you run.

In DAG, read-audit-logs_2010_2013.ps1 script will index the data of the mailbox server only where this script is running. So it is required to enable this script on all servers in DAG.
