Hi Erick, it would seem that Vincent's answer has answered my question.
Just curious, if I decide to drop just the legal hold feature, what plan should i be looking at so that users can use the latest Outlook for Mac ver 15.6 and download the full suite of Office applications when they become available? I understand that Office365 Enterprise E3 is on the Enterprise platform. Will that be of any concern when it comes to selecting a plan?
