Nice link:
In a hybrid deployment, which is an environment where some mailboxes exist on your on-premises Mailbox servers and some mailboxes exist in a cloud-based organization, you can perform In-Place eDiscovery searches of your cloud-based mailboxes using the EAC in your on-premises organization. If you intend to copy messages to a discovery mailbox, you must select an on-premises discovery mailbox. Messages from cloud-based mailboxes that are returned in search results are copied to the specified on-premises discovery mailbox.
