SharePoint folders and re-sharing permissions with external parties

[RobbieJiang]

Hello

I have a site in our company, that has been requested to share certain folders with external parties (not in our domain) and to also allow them to reshare the folders.

I have tried several different ways, from link sharing, to adding them to the users allowed to edit.

The end users can see the files and do what they need, but are not allowed to re-share it (this is a screenshot from 1 of the external shared users)

Please help

Thanks

I take it no one knows, or the question doesn't make sense?
