Hello, I'm using the MIP SDK to apply labels. I'm using the IsLabeled function to skip applying a label if one has already been applied. However, I've encountered files where the IsLabeled value is true, but the Label value is null, and when I open the file, no label is actually applied. Can you explain more about the IsLabeled function and in what scenarios this case might occur?

Hello @ 정용우 Thanks for the question and using MS Q&A platform. The IsLabeled function in the MIP SDK is designed to check if a file has a label applied, but it may return true even when the Label value is null due to several reasons. One possible scenario is that the file may have been marked as labeled in the metadata, but the actual label information might not be accessible or intact. This can happen if the label was previously applied and then removed or if the metadata has become corrupted or incomplete. The SDK relies on the metadata to determine the labeling state, and if the metadata indicates that a label was applied, IsLabeled will return true, even if the actual label data is not present. It's important to ensure that the file's metadata is intact and that the label being read still exists in the Microsoft 365 service. If the label has been deleted or if the metadata is not properly maintained, it could lead to this inconsistency.

If the value of FileHandler.Label is null, why does the IsLabeled function return true?

@Ganesh Gurram Thank you for your answer. I was late to check because I was busy with my schedule. In my case, if I apply the online template recommended by the PowerPoint desktop app and save it, that situation will occur. Please refer to the image below.

@정용우

Thank you for the update and for providing additional information.

Based on the image you provided; it seems like the label is not being properly applied to the file even though the metadata indicates that the file is labeled.

One possible reason for this could be that the label policy associated with the label has changed or been deleted since the file was labeled. If the label policy is no longer available or has changed, it could result in the label not being properly applied to the file.

Another possible reason could be a bug or issue with the MIP SDK or the labeling process itself. I would recommend checking the version of the MIP SDK you are using and ensuring that it is up to date. You can also try applying the label using a different method or tool to see if the issue persists.

If the issue persists, I recommend reaching out to MS support for further assistance. They may be able to provide more specific guidance and help troubleshoot the issue.

After checking the metadata, I found an unknown label created with a different tenant ID. I just needed a sample, so I applied the template and saved it without making any changes. Is the template I received, with the label from another tenant ID, uploaded to Microsoft as a template?
