Cause

The Get-ExchangeServer command shows short names for all Exchange servers

Solution

Launch the NetBackup Administration Console and go to "NetBackup Management" > "Host Properties" > Master Servers > "Distributed Application Restore Mapping" and Provide the name of the application host and the name of the component host as follows:

Application host            Component host
Virtual name of DAG     Physical name of Node 1
Virtual name of DAG     Physical name of Node 2
Virtual name of DAG     Physical name of Node 3
Virtual name of DAG     Physical name of CAS server
Exchange host name     Off-host machine name

To make sure that this configuration works, add both FQDN and short name for each server, for example:

DAG-name.domain   Mailbox-server.domain
DAG-name               Mailbox-server
 

In all Exchange servers configure both "Netbackup Client Service" and "Netbackup Legacy Network" services to be started with a user with a unique name as it is explained in the "NetBackup™ for Microsoft Exchange Server Administrator’s Guide":

Create a user account that has a mailbox with a unique name. A unique name is one that does not already exist within the Exchange Organization. This
name cannot be contained as a set of characters in an existing name.

For example:EXCH1is entered as the unique mailbox name, and other mailbox names such asEXCH1BACKUPorBACKUPEXCH1exist. The backup or restore of individual mailboxes or both fail.
