Hello,
As a school, we have an Office 365 subscription that we will ONLY use to deliver Office 365 Pro Plus to our student for free. We would not like at all to use any cloud services.
Active Directory synchronization between our on premise AD and O365 is enabled and working, with password sync. Office Pro Plus licenses ONLY are assigned to students with PS script, working well also.
As I was testing the user experience, I saw that when a user is logged on at portal.office.com to download and install Office, there's a ling "Edit my About me page" in the Office 365 settings.
Thru this link, I discovered that any logged on users has access to a personnal page (kind of mySite?!) and also to a team site with editors rights. When they access for the first time to their personnal page, a SharePoint profile is created, but when I try to edit the personal site, I'v got a "this user doesn't have a personal site".
First of all I deleted the 2 SharePoint site collections (domain.sharepoint.com and domain-public.sharepoint.com). But I can't delete domain.sharepoint.com/search and domain-my.sharepoint.com; the delete button is greyed out.
The only workaroud for now was to remove permissions on the site domain-my.sharepoint.com.
But I really prefer a way to disable SharePoint!
