Is there a way to set a file size limit for external sharing in SharePoint Online?

Question

Hello, we are in the processes of updating our SharePoint/OneDrive governance, particularly around External Sharing. My company would like to restrict the file size limit to 250mb but only when externally sharing. Is this possible? Any solutions?

Hi @Adam Watson ,

AFAIK, there is no OOTB way to set a size limit to a file for external sharing. All external sharing settings we have access to are shown as below via the URL:

As to your requirement, you have to develop a solution by yourself. Or you can share your idea here: SharePoint UserVoice. It is a place for customers provide feedback about Microsoft SharePoint products. What's more, if a feedback is high voted there by other customers, it will be promising that Microsoft Product Team will take it into consideration when designing the next version in the future.
