Cannot Apply Sensitivity Label to PDF File – No Encryption Present

(0) ShareShare
ReportReport
Posted on by 54

Hi all,

I am facing an issue when trying to apply a sensitivity label to a PDF file stored in SharePoint. The error message I get is:

Error: Sensitivity label cannot be applied at this time due to the nature of file's encryption.

However, I can open the PDF file normally, and it does not seem to be password-protected in any way.

Has anyone encountered this before? Is there a way to apply a sensitivity label to such files?

Any guidance would be greatly appreciated!

Thanks in advance.

    Hi @asit00,
     
    Do you have the Microsoft Purview Information Protection Client? As a workaround you might be able to label it from that client. Sync or download the file to your File Explorer and label it from there.

    hi Expiscornovus

    Yes, I already have the document library enabled for sensitivity labels — as you can see in the screenshot, I’m able to set labels on other files and it works fine. The problem is only with this one specific PDF file, which is giving the encryption error.

    Hi @asit00,
     
    I was interested if you could reproduce the issue with the same pdf file on your Windows OS system via the client. That might isolate the issue/symptoms.
     
    That's why I was double checking if labelling it via the client on your windows machine instead of via the browser in a SharePoint document library metadata made any difference.
