Hi Enrique Fleischmann,
Thank you for reaching out.
You can purchase OneDrive Plan 2 to increase your storage. If you have fewer than five licenses, you can manually increase the storage up to 5TB per user by going to the SharePoint Admin Center → Settings → OneDrive storage, and entering a value between 1024GB and 5120GB.
However, for unlimited storage, you need to purchase at least five OneDrive Plan 2 licenses. The five-license requirement is for unlimited storage, not for the 5TB increase.
For more details, please refer to this Microsoft documentation:
