To see a snapshot of all activities and comments on any file in OneDrive, use the details pane on your files. There you can also see who has access to a file.
Note: New comments made on Word, Excel, and PowerPoint files after September 15, 2020 will not show up in the detail pane or activity feeds. However, comments made before that date will continue to show. If you want to add new comments, we recommend using the commenting feature built into those apps.
How to open the details pane
On any file in OneDrive for the web, select Information in the upper-right corner to open the details pane.
If you don't have a file selected and you select Information, you'll see a summary of all the activities that have happened inside your OneDrive. Activities will show for the last 30 days only.
How to manage comments
Under All Activity, enter new comments for items such as PDFs, files, folders, photos, and videos in the comment box.
If you're the file owner, you can turn commenting on or off. Next to the file name, select More , then Disable commenting. Disabling commenting will not remove existing comments from activity. It will only prevent the addition of future comments. To turn commenting back on, select More , then Enable commenting.
To delete an individual comment, select More on the comment and then Delete.
Long comments may be collapsed to save space in your activity feed. Select See more to expand the comment. Note: not available in OneDrive for work or school.
The activity feed in the details pane shows both comments and activity, like renaming files or adding captions and descriptions. To see only comments, select the arrow next to All Activity and filter by Comments. Note: In OneDrive for work or school, filter activities next to View.
