[Onenote] Setting Default Mail Client When Outposting

Background

I usually use onenote's "Email Page" function but the default email client used to sent is always thunderbird.

I tried

• Setting mailto default in windows 10 default open application settings
• Setting preferred Outlook as default mail client

Both not working

Solution

Good job, M$Soft, finally I used the following method to solve (removing registry).

Just remove the key under mail and mailTo folder, and that's it, no need to restart
