- Device & OS
- not provided
- Scenario
- Sharing a Microsoft 365 Family subscription to upgrade an existing free Microsoft email account's storage capacity.
- Observed behavior
- The user needs a way to link an existing Hotmail or Outlook account to an active Microsoft 365 Family plan to unlock additional storage benefits without purchasing a separate subscription.
Ensure you have the login credentials for the main Microsoft 365 Family subscriber account and the exact email address of the Hotmail or Outlook account you wish to invite.
Invite the Hotmail or Outlook Account to Your Family Group
The primary Microsoft 365 Family subscriber can share their subscription by sending an invitation link to the existing Outlook or Hotmail account through the Microsoft account dashboard.
By inviting an existing Microsoft account to your family group, they retain their current email address and files while gaining access to premium subscription benefits.
Go to the Microsoft account sharing page and log in using the primary Microsoft 365 Family subscriber's credentials.
Locate the 'Share your subscription' section on the Services & subscriptions page.
Select 'Start sharing', choose 'Invite via email', and enter the existing Hotmail or Outlook.com email address you want to add.
Have the invitee open their Hotmail or Outlook inbox, find the invitation email, and click 'Accept' to join the family group and activate the storage benefits.
