A Microsoft file hosting and synchronization service.
If the account is included in a Microsoft 365 Family subscription, the expected storage is 1 TB per person. If it still shows 5 GB, use this check path:
- Confirm the subscription type Only Microsoft 365 Family, Premium, and Pro subscriptions can be shared. Personal and Basic cannot share storage.
- Verify the invitation was accepted Shared members must accept the family subscription invitation before the 1 TB benefit is applied.
- Wait for the storage update After accepting the invitation, storage changes can take up to 2 hours to appear. In some cases, storage changes may take up to 24 hours.
- Refresh the storage page Open Manage storage, refresh the page, and check whether the quota changed from 5 GB to 1 TB.
- Check that OneDrive is signed in with the correct Microsoft account A common cause is using a different Microsoft account in OneDrive than the one that was added to the Family subscription. In the OneDrive app, go to: OneDrive icon > Help & Settings > Settings > Account Then verify the signed-in account matches the shared subscription account.
- If the wrong account is connected, unlink and sign in again In OneDrive Settings > Account, select Unlink this PC, then sign in again with the Microsoft account that has the Family subscription benefit. Unlinking does not delete files stored online.
- If the web account shows 1 TB but the app still shows 5 GB Wait up to 24 hours, then unlink and relink OneDrive again.
- If it still has not updated after 48 hours Contact Microsoft support to have the OneDrive provisioning checked.
Also note:
- The 1 TB benefit is for OneDrive cloud storage, not Outlook mailbox storage.
- Outlook.com mailbox storage for consumer plans is capped at 100 GB.
- Each person in the Family subscription gets a separate storage quota; storage is not pooled into one shared 1 TB.
