A family of Microsoft word processing software products for creating web, email, and print documents.
Hi,
Make sure that you have installed the Microsoft Word app on your phone. If it is already installed and you still have the same issue after the recommended troubleshooting, please try using the Microsoft 365 web version or any version or device, and see if you can open the file.
If it can be opened and has been repaired, but still it cannot be opened on your Microsoft Word for Android, please try to clear the cache and data of the app, then uninstalled. Restart your device, then install the app again.
If it does not open the file on any devices, please message the sender if the sent documents were corrupted while uploading. If he can open the original file, please ask him/her to resend it or use OneDrive. It is possible that the file was corrupted.
If you need additional help, please let me know.
Stay Safe!
