Mouse Becomes Unstable While Outlook is Open

Over the past month or so, my mouse / cursor cannot be controlled while Zoom and Outlook are open, the cursor randomly moves across the screen?

I have other video conferencing apps and this only happens with Zoom.

I've tried unplugging my mouse and this didn't help, so it doesn't appear to be the mouse itself (Logitech G Pro). If I close Outlook everything is ok...so it seems like it's the interface with Outlook that's causing the problem. (I'm using Windows / Office 365 Enterprise for business and of course it's up to date.)

My PC is a high end ASUS TUF gaming notebook, with Windows 11, all drivers are to date, as is my Zoom.

Any insight with how to resolve this would be greatly appreciated.
