Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi,
I'm Dyari. Thanks for reaching out.
Microsoft 365 Family can be shared with up to 5 other people, and each person should get their own 1 TB OneDrive storage after they accept the invitation.
Please ask the 6th person to make sure they accepted the invitation using the same Microsoft account they are using for OneDrive and Office.
Ask them to open this page while signed in to their account:
https://account.microsoft.com/services
They should check if Microsoft 365 Family is showing under their account.
Open OneDrive on the web: https://onedrive.live.com > Check the storage again > If they are using OneDrive on Windows, ask them to sign out of OneDrive, restart the computer, and sign in again with the same Microsoft account that accepted the Family invitation.
The Family organizer can also go to:
https://account.microsoft.com/family
Remove that person from the family group, then send a new invitation again.
