Hello SuSu,
We definitely understand the want for the program to be placing the settings as expected rather than forcing the program to open specific files as desired. We have read through this thread and see the steps that have been tried and are looking to see
if there is anything further that can be done.
From the testing done on a Surface Studio directly after an office installation, Microsoft Office programs should be able to function as expected and default to opening every Word document in a vertical scrolling view. We were unable to replicate the issue
described on our own Surface Studio.
On the Surface Studio we installed Microsoft Office 365, then opened Word 2016 and selected the horizontal view and closed Word and restarted the Surface Studio. Any documents opened afterwards will show up in the previously designated horizontal view. When
we change the setting back to vertical view and close Word and restart the Surface Studio, any word documents opened afterwards are opened in the vertical view.
Again, we are looking further into this functionality and will respond if any helpful information is found regarding this situation.
Thank you~
Mason L.
