Question details
The user is unable to use the PDF search function in the Microsoft 365 Android application because the on-screen keyboard does not pop up, and there is no accessible Search or Enter button to execute the query.

- Product
- Microsoft 365 for Android
- Device & OS
- Android
- Scenario
- Searching for specific text within a PDF document using the Microsoft 365 mobile app.
- Observed behavior
- When tapping the search bar inside a PDF, the keyboard fails to open. Even if text is copied and pasted into the search field, the search button or Enter key remains unavailable, preventing the search from executing.
Ensure that your Android device's default keyboard is functioning correctly in other applications, and verify that the PDF file you are trying to search is text-searchable rather than a flattened scanned image.
Clear App Cache and Test Multiple PDFs
Perform fundamental troubleshooting steps to resolve temporary app glitches that might be preventing the keyboard interface from loading.
Often, a bloated cache or a corrupted temporary file can prevent UI elements like the on-screen keyboard from triggering properly inside specific modules of an app.
Navigate to your Android device's Settings app and select Apps or App Management.
Scroll through your installed applications, find Microsoft 365, and tap on it to open the App Info page.
Tap on Storage & cache, then select the Clear cache button. Do not select Clear Data unless you are prepared to sign back into your account.
Tap Force stop to completely close the app. Reopen Microsoft 365 and attempt to search within a completely different PDF file to rule out document-specific corruption.

Update or Reinstall the Microsoft 365 App
Fix underlying software bugs or corrupted installation files by applying the latest updates or performing a clean installation.
Use WPS Office to Seamlessly Search and View PDFs on Android
If Microsoft 365 continues to experience bugs with its search functionality, consider switching to WPS Office. It provides a robust, built-in PDF reader that allows you to reliably search text, annotate, and view documents without frustrating keyboard glitches.
- 1. Install WPS Office: Download and install WPS Office for free from the Google Play Store.
- 2. Open Your PDF: Launch the app, navigate to your files, and open the desired PDF document.
- 3. Search Your Document: Tap the Search icon at the top of the screen and use the fully supported on-screen keyboard to instantly find your text.

Frequently Asked Questions
Why does the keyboard not appear when tapping the search bar in Microsoft 365?
This is typically caused by a bug in the app's user interface rendering on certain Android versions, or a temporary conflict between the Microsoft 365 app and your specific third-party keyboard app (like Gboard or SwiftKey).
Can I bypass the keyboard issue by pasting text into the search bar?
Unfortunately, no. Even if you manage to paste text into the search bar, the Microsoft 365 Android app currently lacks a dedicated on-screen 'Search' or 'Enter' button within the PDF viewer UI. Without the keyboard's return key, the search cannot be executed.
Will clearing the Microsoft 365 app cache delete my saved PDF files?
No, clearing the app cache only removes temporary files used to speed up the app. It will not delete your documents. However, if you choose the 'Clear Data' option, you may need to sign back into your Microsoft account, though your OneDrive files will remain safe in the cloud.
How do I report this persistent PDF bug to Microsoft?
You can report the issue directly through the app by navigating to your profile settings and selecting 'Help & Feedback'. Be sure to include your specific Android device model, OS version, and the Microsoft 365 app version to help their support team investigate the bug.
