Easily comment on Microsoft Office files in Google DriveAndika Pratama
Google has made it easier to comment on Microsoft Office files in Drive. Without converting the files, you can comment, assign tasks, and mention your colleagues right in the Drive preview pane.
The person on the other end who is using Microsoft Office to open the file can see the comments that you’ve made and reply to it from there. The feature is also available for PDF and image files.
