Office 365 Basics

Hey Florian Maaß,

Don't worry about coming off as a fool, we all started our journey in O365 at some point, and it is a new and confusing world when you come from the rigid structure of on-prem where your applications are much more subscribed.

Suddenly you are in the cloud and there are so many shiny things, and options to play with.

To answer your question, group/company storage is setup and intended to be used in SharePoint. You can either create a document library in there directly, or what I would do in your case is go with a Team. Teams by default create with a files section, that is actually just a document library under the covers. This would give all your users an application they can use to chat, communicate, and share files easily.

OneDrive can be used to do this with 10 users, you would just have to create a folder in one persons onedrive and share permissions out. But onedrive is tied to the user. Say you do this in yours, then you win the lottery and leave, well then the company files by default go with your account when its removed.

As such SharePoint (and by extension Microsoft teams) would be the recommended option here as it is shared group storage, it is tied to the tenant (not a user), and it really does have the best level of controls, permissions, and sharing options.

Hope this helps!
