Yes, It is the Archive Mailbox setting that can be enabled under the person's Exchange Settings.
I have it set for all email instead of 2 weeks.
You're missing the point. Outlook creates a PST archive... If you enable online archive within O365 then it is cloud based. What are you trying to access?
I think you are misunderstanding what I am saying...
When I open Outlook on the Web App I have a special inbox called Archive that isn't a folder inside the normal inbox but a separate inbox inside my account...
When I view my Outlook email in the Windows 8 client, I see all my folders from my normal Mailbox but not the Archive Mailbox...
