Microsoft OneNote Customer Service Issues

I am interested in purchasing Microsoft Office and OneNote as I am specifically looking for software that can instantly convert handwriting to text, including mathematical symbols accurately. After researching online and consulting with friends, I have not been able to find a solution. An example that showcases this feature can be seen on YouTube in a clip titled "Hunger Games meeting with whiteboard" around the 20-second mark where handwriting is converted to text seamlessly. I am reaching out to the customer service team for assistance in finding software that can perform this task. Thank you for your help.

Hello, I used OneNote on my Samsung tablet with my school email ([redacted]) which is now deactivated. This led to the loss of my university notes from the past 2 months. I'm wondering if it's possible to retrieve my lost notes by changing the account email forcefully since my former school informed me that the email address cannot be recovered. If recovering the account is not an option, could the notes be recovered instead? Thank you.

Hello, I hope you're well. I'm facing some issues accessing my OneNote account where I stored many important notes. I was living in Greece when I created the account, but now I have moved to Germany and cannot log in. The account is linked to my email [redacted] Unfortunately, I no longer have access to my old Greek phone number +[redacted]78. When I try to log in using my email, I'm not receiving the necessary verification code. Thank you for your help. Best regards, A. Heilenko
