Journaling in O365
Although supported in Office 365, Journaling is a legacy feature typically used to capture messages from the transport pipeline and deliver them to an archiving system or service. In Office 365, you can journal messages to an SMTP address, typically an on-premises mailbox or a third-party archiving service. You cannot select an Office 365 mailbox as the journaling (target) mailbox.
The recommended archiving solution is to preserve message in-place using In-Place Hold or Litigation Hold. In Exchange Online, this preserves messages in the user's primary mailbox and archive. See https://technet.microsoft.com/en-us/library/dn790612.aspx for more info.
If you use unified hold from the Security and Compliance Center, you can preserve data across Exchange Online, SharePoint Online (including OneDrive for Business files) and Skype for Business. Recently announced functionality also allows you to capture social media content from Facebook, LinkedIn and Twitter in Office 365. All archived data is available for https://support.office.com/en-us/article/eDiscovery-in-Office-365-143b3ab8-8cb0-4036-a5fc-6536d837bfce.
Journaling is available, but you cannot use an O365 mailbox for the target. Any O365 mailbox. The documentation is here: https://technet.microsoft.com/en-us/library/jj898487(v=exchg.150).aspx
Litigation/In-place hold is the preferred method, but it always depends on the requirements.
