Microsoft recently introduced a new feature of commenting in SharePoint Online lists and Microsoft lists. Using this feature users will be able to add and delete comments on list items. Users can view all comments on a list item and filter between views that show comments or activity related to an item in details pane.
Microsoft has started rolling out this feature to all SharePoint Online tenants in December 2020 release, see Roadmap.
Where can you find Comments options?
Comments options are currently located at below three places in SharePoint Online/Microsoft lists:
List view
Users can see which list items have comments when they access the SharePoint Online list view or Microsoft list home page. Comments option will be shown on command bar when you select a list item as well as at the right hand side of Title column. When you hover over on comments icon it will show you the count of comments added to the list item.
Display/Edit form
By default, users will see a new comments pane alongside the list item form when they access a list. Users can toggle the comment pane visibility by clicking the comments icon. When you hide comments, the pane does not collapse. The comments pane will be closed by default for lists customized by Power Apps.
Details Pane
Users can see the Comments and All activity related to list item on details pane. Users can filter views that show comments or activity by using the dropdown under “More details” section.
Permission Considerations
Comments follow the permission settings inherent in SharePoint Online and Microsoft Lists.
- Users with read-only permission can only view comments.
- Those with list edit permission can make comments as well as delete comments; editing comments is currently not possible.
Where the Comments will be stored?
Comments are stored in the schema for each list, which is based on the SharePoint storage platform.
Working with SharePoint REST APIs
As comments are stored within the list schema itself and not with list items, it is not possible to fetch comments using $select with /items endpoint. However, you can get the list item comments using below endpoint:
https://<tenant>.sharepoint.com/sites/<site>/_api/web/lists/getbytitle('<list-name>')/GetItemById(<item-id>)/Comments()
//OR
https://<tenant>.sharepoint.com/sites/<site>/_api/web/lists/getbytitle('<list-name>')/items(<item-id>)/Comments()For more information on working with comments using SharePoint REST APIs, check:
- GET SharePoint list item comments using REST API
- Add Comments on list item using SharePoint REST API
- Delete Comments from list item using SharePoint REST API
- @mention people in list comments using SharePoint REST API
Working with JSON Formatting
Currently it is not possible to get the actual list item comments value using JSON formatting. But, you can get the count of comments added to list item using [$_CommentCount] which is an internal name of SharePoint list column that returns the count of list item comments.
Check how you can get comments count and show it in SharePoint list view at: Working with SharePoint Online/Microsoft List Comments using JSON Formatting.
Current Limitations
- Editing comments is currently not possible.
- Any user can delete the list item comments. Currently there is no way to disable deletion of comments.
- Maximum characters limit in list comments: 2000 characters
- Classic lists that are not yet built to show up in modern user interfaces, like Task lists, will not have this commenting feature.
- Commenting on lists in Teams is not available with this release.
- Comments are not indexed by Search.
Enable/Disable Comments
Currently it is not possible to disable commenting at the site or list level. Microsoft is working on the new feature which will allow users to enable/disable the comments for individual SharePoint lists. However, Admins can enable/disable this feature at the organization level by changing the CommentsOnListItemsDisabled parameter in the Set-SPOTenant PowerShell cmdlet:

What’s Next?
- Currently it is not possible to disable commenting at the site or list level. Microsoft is currently working on this feature update, more information at: Enable/Disable the comments for a SharePoint Online/Microsoft List.
- @mentions in comments:
- Get a colleague’s attention to an item in a list by @mentioning them within list comments. That person will receive a notification and a link that takes them directly back to the item, to review the comment and take the requested action.

Hi, it seems like the email button “Go to comment” has an incorrect URL. It opens the root sitecollection OLD News feed instead of the specific site collection list in which the comment was added… The URL:https://xxx.sharepoint.com/SitePages/Startsida.aspx?ID=1&commentId=1&e=bM1bDrcaYU%2DaV30DR0nw6Q&at=15&CT=1632903431322&OR=OWA%2DNT&CID=1c47f71a%2Df055%2D139d%2De61f%2D13bb9aad8439.

Thank you very much Monty. Unfortunately, we cannot hide this button using SharePoint OOTB features. You can hide it by injecting custom CSS on a page using SPFx application customizer (Not recommended by Microsoft).

then I get the following response:
List ‘SitePages’ does not exist at site with URL ‘https://tenant.sharepoint.com/site_name/company’

If you could also describe this, that would be very nice.

Use ‘Site Pages’ instead of ‘SitePages’. Try using: https://tenant.sharepoint.com/sites/site_name/_api/web/lists/getbytitle('Site Pages’)/items(368)/Comments()

In the classic SP I used a comments field in the list that showed text comments and it added date and time. Is this function gone in the new SP Modern experience? The new comment style looks more like a social media comment feature (including avatar). I added a comment field (multiple lines of text) to my new list, but it does not update with date and time. Having the old style of comment feature for was great for tracking work done on each list item. Thanks

You can still use Multiple line of text column with “Append to existing text” setting enabled in modern experience to capture the comments. Try enabling this setting for your multiple lines of text column.

Yes, this is not possible as user should have edit permission on list item in order to comment on it. Also, no news from Microsoft about changing this functionality in near future.
