Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello
There is no way to simply switch from a higher plan to a lower plan. YOu will have to cancel the family plan first. Then subscribe to the personal plan separately.
Please go to https://account.live.com
Sign into your Microsoft account. Then go to Services. Click on Manage for the subscription plan you want to cancel.
Don't sign up for the personal plan yet. After you cancel the family plan, it is still effective until the expiration date. Then you can sign up for the personal plan. As long as you use the same Microsoft account, there won't be data loss.
