Hi Ylx_858,
Thanks for posting your concern in the Community. I hope you're having a nice day. Let's address your concern.
Have you tried following this steps to use OneNote’s Use Pen as Pointer feature:
1. Click Draw, then expand the pen gallery by clicking the
downward-pointing arrow in the bottom right corner of the gallery.
2. Select Pen Mode, then choose Use Pen as Pointer.
Note: If you find yourself using this feature frequently, right-click Use Pen as Pointer and choose Add to Quick Access Toolbar to pin the command to the top of your OneNote window.
When you enable Use Pen as Pointer, you can use your mouse, touchscreen, or your tablet’s pen to draw on the screen to attract your audience’s attention–and anything you draw will disappear after a couple of seconds, so you won’t permanently mess up your
notes.
If you're having issues enabling it, kindly make sure that all Office updates are installed. To check, see this
link for instruction on how to install
updates. I would suggest that you start OneNote in safe
mode, and see if there are add-ins that might be causing this.
If the issue also occurs in safe mode, try
repairing OneNote. If the issue
still persists after repairing OneNote, I highly recommend that you reinstall
Office. There's a possibility that there are corrupted system files that's hindering OneNoteto work properly.
