I am trying to purchase a SharePoint Online account. I already have an Office 365 account and purchase Project 2016. Now when I want to purchase the SharePoint online account, I get the message "sorry, you cannot add this to your current account. .... You need to sign out and create a new account"?
I already have two Office accounts. One is my personal Office 365 that has word, powerpoint, excel etc. The other is a work account that has Project 2016. Why do I need a third one?
Why is that? Why do I have to create another account?
