If you are running Microsoft Office 2007 Standard, 2010 Standard, or 2013 standard and aren’t seeing the personal archives, that is because those versions aren’t supported. You want to make sure you have the correct licensing if you want your end users to see the Online Archives section within their Outlook client. Now you can always enable the Outlook Web App (OWA) for them to manage it, but it is something to keep in mind and check.
You can see the supported versions of Microsoft Outlook that work with Online Archives on the Microsoft site: License requirements for Personal Archive and retention policies.
In the new wave 15, Exchange 2013 environment you can manage the archive polices within the Exchange Admin Center under the compliance management section.
