The owner of a Microsoft 365 Family, Premium and Pro subscription can share their benefits with up to five people. Accepting this invitation grants you access to the subscription benefits including 1 TB or 2 TB shared OneDrive cloud storage and desktop apps like Word, Excel, PowerPoint, and Outlook.
Note
Starting October 8, 2026, all new (including expired and repurchased) Microsoft 365 Family and Premium subscribers get 2 TB of pooled OneDrive cloud storage, and Microsoft 365 Pro subscribers get 5 TB pooled storage. From May 2, 2027, all existing Microsoft 365 Family and Premium subscribers will get 2 TB of pooled cloud storage when the subscription renews. Pooled storage means the cloud storage allowance is shared across all members of a shared subscription. Each person's mailbox, files and folders continue to remain private. All subscription types can be extended up to 10 TB to give everyone even more OneDrive storage.
Once you accept and join their shared subscription, you will automatically be added to their Microsoft Family group. If you're in another family group, you'll have to leave that one first before you can accept this invitation.
