Microsoft is retiring one of its Office 365 versions, and replacing it with an updated SKU before the end of calendar 2015.
The Office 365 E5 SKU will be replacing the current E4 version, officials said on July 13. The Office 365 E5 SKU will include Skype for Business (Lync) with support for features including Cloud PBX and Meeting Broadcast; new analytics features, like Power BI Pro and Delve Organizational Analytics; and new advanced security features, such as eDiscovery, Customer Lockbox, Data Loss Protection and Safe Attachments.
Office 365 E4 sells for $22 per user per month. It includes Skype for Business with Enterprise Voice and unified messaging; the full suite of locally downloadable Office apps; and Power BI for Office 365 (which is being superseded by Power BI pro).
