Give sharepoint edit permissions to users on one column only

Occasional Contributor


I am having the certain problem.

I have a sharepoint list shared to users with edit permissions. In this same sharepoint list I have succesfully shared the list to an external user with view only (READ permissions).

On one of the columns in the sharepoint list I need this person with read permission to be able to edit and comment on the rows , just in this column.

I don't see a way I can do this even with disabling inherritance permisions on this library. Can you please advise.

I do not think you can do it in native SharePoint in 1 list.
A simple solution could be a PowerApps form (with comments field) and a Power Automate executed by a system account with write access on the list.

@SYLV1 thanks for your answer


Isn't there an easier way to do this can you direct me to a step by step guide to resolve this problem?

@lazo111 no, I don't think there's any other way to achieve this.

There is no colum security level in native SharePoint. If a user can edit an element he can edit all the available columns (including title). He can also add new values.
I do not see an easier or better way to do it on 1 list.

Only other option i can see so far is with 2 lists. List 2 with hidden title, lookup columns on List 1 and specific contribute level access (without creating items). But that would mean creating the items twice to manage comments. (why i proposed a power Apps comments form with Power Automate to update)

unreal that Microsoft doesn't have this feature yet and google sheets does. 2 lists would be a nightmare . Do you perhaps have a tutorial on how to guide me with the powerapp and automate solution. I still want the external user to see the whole list so when he clicks a field in the column needing to edit will it take him to a powerapp form and then the update will happen automatically with the flow?
Hello !
No tutorial except advise to look at some Youtube videos and create the "Getting started with Power Apps"" Template.

I do not have the full context, but i would create a Tablet canvas app, connect the SharePoint List and use it as a datasource for a gallery ( on container for responsive design). Then Add a button to open a popup with comments / save / cancel. Finally save the comment via PowerAutomate on Button after validation.
The app could be exposed in a SharePoint page or accessed directly on a tablet/phone

@SYLV1  thanks Sylv, it sounds very complicated, I have found a 3rd party solution for this. 


I don't want guests to be opening apps to write comments , thanks again
