Fix Files App Disabled in Office for iOS Document to PDF
Question details
The user is unable to select files from the native iOS Files app when using the Document to PDF feature in Microsoft Office Mobile, as the option is grayed out or disabled.

- Product
- Microsoft Office Mobile
- Device & OS
- iOS
- Scenario
- Attempting to convert a document to PDF using the Microsoft Office app on an iPhone or iPad.
- Observed behavior
- The Files app selection control is disabled within the Document to PDF tool, preventing the user from browsing or selecting documents stored in iCloud or local device folders.
Ensure your Microsoft Office app and iOS system are updated to the latest versions, as Microsoft frequently releases patches to address known interface bugs.
Use the 'Export' Feature as a Workaround
Bypass the standalone 'Document to PDF' tool by opening the file directly and using the export function.
Since the Files app control is disabled in the dedicated PDF tool, you can achieve the exact same result by opening the document first and then exporting it as a PDF from within the viewing interface.
Open the native iOS 'Files' app and locate the Word document you want to convert.
Tap the document to open it. If it doesn't open in Office by default, long-press the file, tap 'Share', and select the Office app.
Once the document is open in the Office app, tap the three-dot menu (More options) in the top right corner, select 'Export', and then choose 'PDF'.
