Dear LU Matty FC,
Thanks for your updates.
I’d like you to check whether you are using the latest version of the Office applications. If no, I suggest you update the version, restart the computer and then do a test to see the result. About running an Office repair, please check whether you go to Control Panel with the computer administrator right>Programs>right-click on the Office applications’ icon>Change>Online Repair. If no , do that as well to see the result.
I also suggest you reconnect the external monitor, set up the dual monitor via the steps in the article and then log into the computer with another local user account to see if the issue happens. As the issue seems to happen in multiple users in your company, I suggest you click on File>Feedback>Send a Frown as soon as possible to report the issue to our related team directly so that they can involve more resources on checking the issue in your environment further.
Best Regards,
Cliff
