Disable or enable Exchange Search
Applies to: Exchange Server 2013
By default, Exchange Search is enabled for all new mailbox databases and doesn't require additional configuration. However, if you want to stop Exchange Search from indexing mailbox content, you can disable it for individual mailbox databases or for an entire Mailbox server.
Disabling Exchange Search impacts the functionality and performance of the full-text searches that are performed by your users using Outlook in online mode or on Windows mobile devices.
In-Place eDiscovery also relies on Exchange Search. If you disable Exchange Search for a mailbox database or for a Mailbox server, In-Place eDiscovery searches won't return any messages from the database or server.
