Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi, I'm John! I will help you with this.
If you purchased a Microsoft 365 Family subscription, you can share it with up to 5 other people. Each person will need their own Microsoft account.
Please see "Share your Microsoft 365 subscription" https://support.microsoft.com/accounts-billing/subscriptions/share-your-microsoft-365-subscription
Are you using Microsoft 365 Family or Microsoft 365 Premium? Also, do you see a Share button on the page, or are you getting an error message?
