Journaling rules for Office 365 with Exchange are not subject to the differences between standard and premium journaling that apply to Exchange on-premises. However, there are other restrictions for journal rules in an Office 365 with Exchange environment that you must be aware of. For example, you can create a maximum of 10 journal rules.
The domain name must be a non-existent domain. You must use the same domain for the remote domain, the mail contact, the Send connector, and the journal rules.
Before You Begin
