Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Victoria Simpson1,
Thanks for visiting Microsoft Community.
Are you the owner of a Microsoft 365 Family subscription? Was your personal subscription redemption code included with a device? The features and prices of Family and Personal subscriptions are different. For example, when switching subscriptions, the days of a Personal subscription will be converted to Family subscription days at a certain ratio. Therefore, it may not be possible to use your Personal subscription redemption code to offset the cost of a Family subscription. However, I recommend contacting our online chat support directly via the specific steps in this thread to evaluate whether your situation can be converted to a certain number of Family subscription days at the time of redemption.
I hope your issue gets resolved.
Best Regards,
