Question details

The user wants to know if the separate 1 TB OneDrive storage quotas provided to six individuals under a Microsoft 365 Family subscription can be merged into a single 6 TB storage pool.

Can Microsoft 365 Family Storage Be Combined into One 6 TB Space?

Product: Microsoft 365
Device & OS: not provided
Scenario: Managing cloud storage limits and attempting to maximize available OneDrive space for a single user under a family plan.
Observed behavior: Microsoft 365 Family distributes storage as 1 TB per person, and the user is unable to find an option to pool or unify these allocations into one combined 6 TB account.

Before you start

Verify your current OneDrive storage capacity by logging into your Microsoft account and navigating to the storage management section to see how much of your individual 1 TB allocation is used.

Solution 1Recommended

Use Shared Folders to Distribute Storage Load

While you cannot physically merge the six 1 TB accounts into a single 6 TB pool, you can use the other family accounts to store large files and share them back to your main account.

Microsoft 365 Family strictly allocates 1 TB of storage per user. The accounts remain entirely separate for privacy and security reasons.

To work around this limitation, you can create secondary Microsoft accounts (up to 5 additional ones), invite them to your Family plan, and use their 1 TB allocations by sharing folders.

Create or log into a secondary account

Create a new folder

Click on 'New' and select 'Folder' to create a dedicated space for large files (e.g., 'Archive Storage').

Share the folder with your main account

Right-click the newly created folder, select 'Share', and enter the email address of your primary Microsoft account. Ensure you grant 'Edit' permissions.

Access from your main account

Log back into your primary account. Go to the 'Shared' section in OneDrive to access, edit, and manage these files without them consuming your primary 1 TB storage quota.

Use Shared Folders to Distribute Storage Load

Storage Allocation Rule: Files uploaded to a shared folder count against the storage quota of the account that originally created and shared the folder, not the account accessing it.

Solution 2

Purchase Additional Storage for a Single Account

If a single user strictly requires more than 1 TB of space on their primary account, they can purchase additional OneDrive storage individually.

Frequently Asked Questions

Can I assign two of the six Microsoft 365 Family licenses to one email address to get 2 TB?

No. A single Microsoft account can only hold one active Microsoft 365 license and is limited to a single 1 TB base storage allocation. You must use a separate email address to claim another 1 TB.

If I cancel Microsoft 365 Family, what happens to the 1 TB storage for each user?

If the subscription expires or is canceled, all six accounts will revert to the free 5 GB OneDrive storage limit. Users will be able to view and download their existing files but won't be able to upload new ones until they delete enough files to get under the 5 GB limit or purchase more storage.

Can I see what files my family members are storing in their 1 TB space?

No. Even though you share a Microsoft 365 Family subscription, each person's OneDrive account remains completely private. You cannot view their files unless they explicitly share a file or folder with you.
