The Exchange page appears.
Click an Exchange database.

In the Subclient section, click the subclient for which you want to enable block-level backup.
The subclient page appears.
In the Settings section, click the Optimize for message level recovery slider.
Note: After you enable block-level backup on a subclient, the next backup operation is always converted to a full backup operation.
