The borders on tables in Microsoft Word keep disappearing for all people in my company
For all users at our business, when we open up Word files with tables within them, the borders of the tables disappear and we have to manually add them back. Does anyone know why this happens and what we can do to fix this?

- Word Documents are stored in SharePoint
- User 1 opens in Word application, table styles are present
- User 2 opens in Word in browser and selects to edit the document in Word app
- The switch from browser to Word app appears to remove the table styles with borders and replaces with no borders style

If possible, share such a problematic document with the forum so that we can have a closer look. Of course, any personal information should be removed from the document before you share it.
