Dear GMCC_1910,
Welcome to the Microsoft Community.
Based on the information you have shared, I understand that you want to change your age information in your Microsoft account and I understand your feelings.You can change your birthday age in your personal information section after logging into your account by clicking the link below: Microsoft account | Your profile
If you can't change your age in the above way, since it involves your account and other personal information, in order to prevent your information from being disclosed in the public community, we suggest you to contact the online support staff to help you to change it:1. Go to this website: Contact - Microsoft Support2. Enter your question in the search box there. For example, subscription/change profile/refund, etc.
3. Now click on Get Help and select Contact Support below.
4. Go to the Products and Services tab and select the Microsoft 365 and Office category or Other Products.5. On the Category tab, select Manage Subscriptions or Other Alternative.
6. Go to Confirmation.7. You can now select the option to chat with a support specialist on your web browser.
Tip: The chat support team has limited working hours, so if you see the last window indicating that you cannot be contacted, we recommend that you try again the next day. If you prefer phone support, you can leave your phone number. This way, they can reach out to you and help you with your problem.I hope this helps and look forward to your updates and feedback.Wish you all the best.
Best wishes
Isabella-MSFT | Microsoft Community Support Specialist
