Hi @Davide Sferrazza,
Welcome to Microsoft Q&A forum.
Thank you for reaching out and sharing your question regarding OneDrive storage. I understand you're expecting a total of 2 TB of storage for your account, based on your Microsoft 365 Business subscription and an additional OneDrive license. I appreciate the opportunity to clarify how storage allocation works in this scenario.
Currently, Microsoft does not support combining storage from multiple licenses into a single user account. Each OneDrive license is designed to provide storage for an individual user, and additional licenses typically extend storage for other users within the organization, not stack onto an existing user's quota.
If your goal is to increase storage for your account beyond the default 1 TB, and you're an end user without admin access, I recommend reaching out to your organization's IT administrator or whoever manages your Microsoft 365 licenses. They can:
- Review your current license setup,
- Apply a Microsoft 365 Extra File Storage add-on to your account,
- Or explore upgrade options such as Microsoft 365 E3/E5, which allow for expanded OneDrive storage (up to 5 TB per user upon request).
If you're managing your own subscription and have admin access,
- Upgrade to Microsoft 365 E3 or E5, which allows for expanded OneDrive storage (up to 5 TB per user) upon request to Microsoft support.
- Purchase the Microsoft 365 Extra File Storage add-on, which can be applied to increase your storage quota.
- Utilize SharePoint Online for additional file storage and sharing needs.
I understand this may not be the outcome you were hoping for, and I truly appreciate your patience and understanding as we work through it.
