You can enable sensitive by default for your tenant - https://docs.microsoft.com/en-us/sharepoint/sensitive-by-default

This will mark files as sensitive immediately at upload and only remove DLP once deemed safe. It doesn’t speed up processing as now you may need to wait in order to share. But it will prevent data leakage from occurring before DLP has a chance to process the files.

    I tested it out and the external user was still able to see the contents of the document.

     

    I ran this cmd from the linked documentation you posted: 

     

     

     

    Set-SPOTenant -MarkNewFilesSensitiveByDefault BlockExternalSharing

     

     

     

     

    Update: Re-read the documentation and this solution doesn't cover OneDrive yet.

     

    "Note

    This cmdlet applies to newly added files in all SharePoint sites. It doesn't block sharing if an existing file is changed.
    The cmdlet doesn't cover files added to OneDrive. We're working to bring this functionality to OneDrive."

     

    My issue is strictly with OneDrive external collaboration. We do not have SharePoint enabled for external sharing yet. 

     

    Is there an estimate of how long this new cmd will be able to cover OneDrive?

    Oh now that it nice.  Not something I had heard of yet but will definitely be checking it out.

     

    Odenkaz - if this does what you are looking to achieve (which I think it will), please can you mark BenSteginks reply as the best response in order that others can easily find this solution. :smile:
