Joining a Microsoft 365 Family subscription should give each invited person:
- 100 GB of Outlook.com mailbox storage
- 1 TB of OneDrive cloud storage
If it still shows only 5 GB email storage, the account is likely still on the free tier and not correctly associated with the shared Family subscription.
Steps to verify and fix:
- Ask the subscription holder (husband) to:
- Sign in to the Microsoft account used to buy Microsoft 365 Family.
- Confirm the Family subscription is active and shared with the correct email address.
- Re‑send the family sharing invitation if needed.
- On the joined account (the one showing 5 GB):
- Make sure the invitation email was accepted using the same Microsoft account that is being checked for storage.
- Sign out of Outlook.com and sign back in with that Microsoft account.
- Check the storage quota on the joined account:
- Go to the Microsoft storage area of the account dashboard using Open account dashboard from the storage article.
- Confirm that the subscription type shows as Microsoft 365 Family and that mailbox storage is 100 GB.
If the dashboard still shows “Free – no subscription” and 15 GB mailbox / 5 GB cloud storage, the Family subscription is not applied to that account and the invitation/sharing setup needs to be corrected.
