Solution 1Recommended

Update and Reinstall the Office Apps

Updating or reinstalling the apps clears corrupt cache files and ensures you are running the latest version with current authentication patches.

Authentication errors like Code 105 are frequently caused by outdated app versions or corrupted sign-in caches. A fresh installation forces the app to request new security tokens from Microsoft's servers.

Check for Updates

Open the Apple App Store, tap your profile icon at the top right, and check if an update is available for Word or PowerPoint. Tap 'Update' if one is listed.

Uninstall the Application

If updating doesn't work, go to your iPad Home Screen. Tap and hold the Word or PowerPoint app icon, select 'Remove App', and then tap 'Delete App'.

Reinstall and Sign In

Open the App Store, search for Microsoft Word or PowerPoint, and download the app again. Launch the app and attempt to sign in with your Microsoft account.

Cloud Backup Required: Ensure your local documents are backed up to iCloud or OneDrive before uninstalling, as deleting the app may remove locally stored files.

Solution 2

Force Restart the iPad and Applications

A simple restart of the applications and the iPad can resolve temporary software glitches preventing successful sign-in.
