A Microsoft file hosting and synchronization service.
Yep - you can share files from a free 5 GB OneDrive account with 20 people, as long as the total size of the files stored in your OneDrive remains within the 5 GB storage limit.
The recipients do not necessarily need a Microsoft account to view or edit the files. You can send an "Anyone" sharing link, or share with specific email addresses. External users may be able to verify their identity using a temporary one-time passcode sent to their email.
You can also choose whether the 20 people have view-only access or permission to edit the files. If you grant editing permissions, they can make changes to the files through their web browser without needing a full Microsoft 365 or Microsoft Office subscription.
To set this up, create your free OneDrive account, upload the files, and use the sharing options to generate a link or specify the people you want to share with.

Sharing options
- Choose Share with "Copy link" to share items with lots of people you might not know personally. For example, via social media or email. Anyone who gets the link can view or edit the item, depending on the permission you set.
- Choose Share with specific people if you want to send the link more privately, with permissions set for specific individuals or groups.
