Adding email accounts without license

parsarvin  I'm a sole proprietor and I had the same question. I understand the answers you gave.

I have a temporary second person working for my firm for a few months. I have created an email user account for her, but have not purchased a license. Could you answer a few more questions I have about the distinction?

1. Does my second user need a license just to access her email even if she doesn't use any of the Office applications?

2.  If my second user already has a license to use the Office software through another entity (her school) can she use the apps (Outlook, for example, for email and Word to edit documents I share with her) without me purchasing a user license for her? 

3. If I want her to be able to access my firm's folders on OneDrive, does that alone mean she needs a license?

Thank you for any info you can share.
