We have a family account and my wife and I both have our own Microsoft logins/OneDrive storage and they're both linked to the licensed family account. We put shared content in the family account and we both have access to it...everywhere.

We also have the latest versions of MS Office installed, everywhere. The cloud-based versions are also available.
