How to add limited access permission on external users on a document library

[stavrama]

Hello everyone,

I have created a custom permission level on SharePoint Online, where i want external users to be able to have contribute permissions without delete.

If i try to share directly a folder inside a document library i get only the view and edit permissions. So i went to the folder, i disabled inheritance and add the users with the appropriate rights.

The problem is though that in order to be able to see the folder, those users must have limited access permission on the document library and this permission appear only when the user send an access request.

Is there a way to avoid it and setup the rights from the start? Is there another way to setup those rights that i am not aware of?

Thanks in advance for your help.

Create a custom permission level: Go to Site Settings > Site Permissions > Permission Levels. Create a new custom permission level with "Add Items", "Edit Items", "View Items", "Open Items", "View Versions", and "View Application Pages" permissions. Make sure to uncheck the "Delete Items" permission.

Grant permissions at the document library level: Go to the document library where you want to grant access to external users. Stop inheriting permissions and remove all existing permissions. Add the external users and grant them the custom permission level you created in step 1.

Grant permissions at the folder level: Navigate to the folder where you want to grant access to external users. Stop inheriting permissions and remove all existing permissions. Add the external users and grant them the custom permission level you created in step 1.

Test the permissions: Ask one of the external users to log in and try to access the folder. They should be able to see the folder and its contents, but not delete anything.
