To stop students from posting replies to individual announcements, you can close an announcement to comments.
If necessary, you can also disable comments for all announcements in a course.
- If your announcements display a lock icon, announcement comments have already been closed to comments. Based on your institution's preference, comments may be disabled by default.
- You may be able to open individual announcements for comments that have been closed. However, if the option to open a comment is not available, your institution has restricted this feature.
