Exchange Online Protection provides cloud-based email protection for Microsoft Exchange Online cloud-hosted mailboxes or an on-premise Microsoft Exchange Server 2013 environment. But what USLs or CALs include rights to EOP? Page 74 of the July 2013 PUR confirms the complete list. More interestingly perhaps, it also confirms when EOP licences are NOT required: for shared, resource, and application-based mailboxes.
The July 2013 PUR is updated so that a Project Online User SL or a Project Pro for Office 365 User SL are valid licensing options for accessing Project Server 2013. See page 36.
