Fix Word Requesting Access to Random Folder When Opening via Acrobat on Mac
Question details
The user encounters a permission prompt where Microsoft Word requests access to a random, grayed-out folder when attempting to open or combine documents using Adobe Acrobat.

- Product
- Microsoft Word for Mac, Adobe Acrobat
- Device & OS
- macOS Sonoma 14.5
- Scenario
- Attempting to combine multiple Word documents into a single file using Adobe Acrobat.
- Observed behavior
- Microsoft Word throws a file permission error and prompts the user to grant access to an inaccessible or random folder, preventing Acrobat from processing the documents.
Ensure that your macOS, Microsoft 365, and Adobe Acrobat are fully updated to the latest versions, as running outdated software often exacerbates inter-app permission conflicts.
Convert Word Documents to PDF Before Combining
Since macOS sandbox restrictions block Acrobat from commanding Word to convert files in the background, manually saving files as PDFs first bypasses the error.
macOS employs strict application sandboxing. When Adobe Acrobat tries to open Microsoft Word to process a document combination in the background, the Mac system blocks the interaction, triggering a false folder access request.
Launch Microsoft Word for Mac and open the first document you want to combine.
Navigate to the top menu bar, click on 'File', and select 'Save As'. In the file format dropdown, choose 'PDF' and click 'Export'.
Repeat the 'Save As PDF' process for every Word document you intend to combine.
Open Adobe Acrobat, select the 'Combine Files' tool, and choose the newly created PDFs to merge them seamlessly.

Grant Full Disk Access to Word and Acrobat
Modifying your Mac's privacy settings can sometimes resolve stubborn folder access requests between third-party applications.

- 3. Merge PDFs Internally: Use the WPS PDF Toolkit directly within the same app to merge your files with zero permission errors.

Frequently Asked Questions
Why does Word for Mac ask for folder access when using Adobe Acrobat?
This happens due to strict macOS app sandboxing policies. When Acrobat attempts to silently use Word in the background to convert a document, macOS blocks this inter-app communication, resulting in a random or grayed-out folder access prompt.
Can I combine Word documents directly in Adobe Acrobat on Mac?
Directly combining native .docx files via Acrobat is notoriously problematic on Mac due to system permissions. The most reliable method is to manually save your Word documents as PDFs first, and then combine those PDFs in Acrobat.
Will updating my macOS fix the Word folder access error?
Updating both macOS and your Microsoft 365 suite is recommended as it can resolve underlying bugs. However, because this issue is rooted in Apple's fundamental security architecture (sandboxing), updates alone may not permanently eliminate the cross-app permission conflict.
