SharePoint Online - Custom Permission

Hi Experts,

I wanted to get a clarification on a permission level.

We have two groups called Internal and External.

  1. Internal users should be allowed to read, edit + delete any documents within the library. (ie) Internal users can delete documents that are uploaded by Internal + External group users.

  2. Whereas External group users can read and edit others documents but they should be allowed to delete only their documents and not other user's document.

What should be best approach to implement this in SharePoint Online using Custom Permissions ?

Thanks,
Murali .

For internal users, we could grant default permission level “Contribute” at library level to view, add, update, and delete all documents:

However for external users, there is no easy way to restrict them only delete their own documents if they have appropriate permissions at library level.

We need to create a custom permission level that remove the delete items permission on the basis of the "Contribute" permission level:

Then use above custom permission level to set unique permissions for documents that do not belong to them. This will enable users in the external group to read and edit all documents, delete their own documents, cannot delete other documents.

How to Set Unique Permissions in SharePoint

In addition, if you have multiple files in your library, this is not suitable for you, because you need to set unique permissions for multiple files one by one. This is not a convenient process, and there is no good way to customize permissions to fulfill your requirement .
