About the Exchange credentials in the client host properties
The Exchange credentials in the client host properties indicate the account that has necessary permissions to perform Exchange restores. The permissions that are required depend on the Exchange version that you have.
See the following topics:
See Creating a privileged NetBackup user account for EWS access.
See Creating a minimal NetBackup account for Exchange operations.
Note the following:
The account that you configured for the must also have the right to "Replace a process level token."
For database restores from VMware backups, the Exchange credentials that you provide must have permissions to restore VM files.
If you want to restore from a VMware snapshot copy that was created with Replication Director, do the following:
If you specify the minimal NetBackup account for the Exchange credentials in the client host properties, NetBackup can back up only active copies of the Exchange databases. If you select in the Database backup source field when you create a policy, any backups fail. The failure occurs because the Microsoft Active Directory Service Interface does not provide a list of database copies for a minimal account.
To use GRT, configure the Exchange credentials on all granular clients.
Alternatively, you can configure the Exchange credentials only on the granular clients that perform restores. In this case, for the entire domain add "Exchange Servers" to the "View-Only Organization Management" role group. Perform this configuration in the Exchange Administration Center (EAC) or in Active Directory. See the following Microsoft article for more information:

These additional items apply to Exchange 2010:
For granular restores from VMware backups, only the Exchange client that performs the granular restore requires configuration of the Exchange credentials. The Exchange credentials are not required for backup or browse operations.
