Long term email archiving\Journaling in Office365

About 6-9 months ago I was looking to migrate a bank to O365 and they have to meet compliance rules about email retention.  Not only retaining email but retaining a read only copy of all email, a.k.a journaling.   Currently we have email journaled to an appliance in house and our Exchange is in house.  The last time I talked to the MS sales guy I was told that there was a method of archiving/journaling in O365.  I am migrating us to O365 soon and can't find any method of journaling.  The Sales guy used the phrase Data Loss Prevention but that doesnt look like journaling, especially since they have a journaling option in O365 already.  My searches have told me that MS does not offer a method to journal online, only external (see below).  Can anyone verify that?  

“Journaling mailbox   The journaling mailbox is used for collecting journal reports. How the journaling mailbox is configured depends on your organization's policies, regulatory requirements, and legal requirements. You can specify one journaling mailbox to collect messages for all the journal rules configured in the organization, or you can use different journaling mailboxes for different journal rules or sets of journal rules. The journaling mailbox specified in a journal rule must be external to your organization.”

Journaling is a bit obsolete now, I'd look into using Litigation hold/In-Place hold instead. Also, the Preservation policies which allow for real immutability. And you can get this for free for any departed users, via the Inactive mailboxes functionality.

If you insist on journaling, you can still use that, however the target mailbox needs to be outside of O365.

Thanks, that makes much more sense.  Not like MS to make finding information easier.  Now I just need to figure out the plans that offer this.  Hopefully it wont take another 9 months.  Thanks.

The E3 plan should be enough, if you really need advanced compliance functionality, you can also take a look at the E5 one. In case you are only interested in Exchange, use the Exchange Online Plan 2 instead, it will be much cheaper.

Most of our clients are using the Business Premium or Pro Plus, for the compliant ones we will use an E3 or greater.
