Office 365 user without license

When you add new O365 user, there is an option to assign no license. But what exactly features will be available for such users?

First, when I logged in to https://portal.office.com I got this:

No nice tiles, no App Launcher icon, no links to any O365 service at all.

I started to open direct URLs for different applications.

I could not open mailbox. I manually requested https://outlook.office365.com and got this:

Newsfeed was not working. I tried only SharePoint Newsfeed, not Yammer.

I was redirected to profile page:

I attempted to request this URL for OneDrive:

https://tenantname-my.sharepoint.com/_layouts/15/MySite.aspx?MySiteRedirect=AllDocuments

But it redirected me to profile page again.

SharePoint site was available without a problem: I uploaded documents, used office web apps to edit documents, etc. When I tried to go to “About me” to look at profile, I got this:

On the other hand, I could manually type my site url and open my profile, edit it, add picture, etc.:

It seems like user can get almost all SharePoint Online functionality, but not other O365 services, like Exchange and Skype for Business.
