I have an Office 365 E3 license that comes with SharePoint online.
Is there any way to create separate Sites for each of my customers within my own account, in a way only each of them can see their own information and no one else's?
I would like that they dont even see the names or sites of any other customers I have. I have only 7 customers, small businesses, and each customer has 2-4 people that would need to see my site, some of them read only and some of them read/write. 4 of them customers use Office 365 as well, and 3 of them has their own email server.
