Sensitivity Label File Support in Microsoft Purview
You have a Microsoft 365 E5 subscription. You create a sensitivity label named Label1 and publish Label1 to all users and groups. You have the following files on a computer: • File1.doc • File2.docx • File3.xlsx • File4.txt You need to identify which files can have Label1 applied. Which files should you identify?

Community Insight
The exam tests the distinction between modern Office file extensions (.docx, .xlsx) and legacy ones (.doc). The common trap is assuming all Word/Excel variants are treated equally by the label policy.
This question tests knowledge of supported file types for Microsoft Purview sensitivity labels. It establishes that while modern Office formats are fully supported, legacy .doc files are excluded from client-side labeling.
Most candidates choose Option C because they assume .doc files are identical to .docx. However, Microsoft Purview documentation explicitly lists legacy .doc as unsupported for client-side sensitivity labeling.

Expert Analysis
Why the Answer Is Correct
Option B is correct because Microsoft Purview Sensitivity Labels support specific file types depending on the application. For Word and Excel, the modern file formats (.docx and.xlsx) are fully supported for labeling in clients like Office apps and Power BI. The legacy.doc format is not supported for client-side labeling due to its binary structure, which prevents embedding the necessary metadata tags.Why the Other Options Are Wrong
Option A is incorrect because it excludes Excel files, which are definitely supported. Options C and D are incorrect because they include File1.doc (legacy Word) or File4.txt. While.txt files can sometimes be handled by specific policies or server-side actions, they are generally not supported for standard client-side sensitivity labeling in the same way native Office documents are. The key exclusion here is the legacy.doc format.Community Comment Notes
Community consensus strongly supports Option B. One commenter noted that 'Dox and txt not supported', highlighting the exclusion of legacy formats. Another user provided a direct link to Microsoft's official documentation confirming that only specific modern Office file types are supported for labeling in office apps.Official Reference
Exam Strategy
Memorize the list of supported file types for Microsoft Purview. Specifically, remember that legacy formats like .doc, .xls, and .ppt are typically not supported for client-side labeling, whereas their modern counterparts (.docx, .xlsx, .pptx) are.
Frequently Asked Questions
Why is .txt not supported for sensitivity labels?
Standard text files lack the container structure required to embed sensitivity metadata tags in most Office clients. Policies may apply to them via other means, but not standard labeling.
Are .doc files really not supported?
Yes, the legacy binary .doc format is not supported for client-side labeling. You must convert files to .docx to apply labels in modern Office applications.
