If Microsoft Word won’t open on your iPhone or iPad, the problem is usually caused by a damaged app install, an outdated version of the app, or a temporary iOS/iPadOS issue. The good news is that there are only a couple of fixes worth trying first, and they solve most launch problems without much effort.
This guide focuses on the two most useful fixes for getting Word open again on Apple mobile devices, with a few notes on when each one is most likely to help.
1. Update Microsoft Word from the App Store
An outdated version of Word can fail to launch properly, especially after an iPhone or iPad update or when Microsoft changes how the app connects to its services. Updating the app is the first thing to try because it is quick and does not affect your documents.
- Open the App Store on your iPhone or iPad.
- Tap your profile icon in the top-right corner.
- Scroll to see pending app updates.
- If Microsoft Word appears in the list, tap Update.
- Open Word again after the update finishes.
2. Offload or Reinstall the Word App
If Word still will not open, the app itself may be corrupted. Removing and reinstalling it often fixes launch problems because it replaces broken app files with a fresh copy.
- Go to Settings on your iPhone or iPad.
- Tap General, then choose iPhone Storage or iPad Storage.
- Find Microsoft Word in the app list.
- Choose Offload App if you want to keep documents and remove only the app, or Delete App if you want a full reinstall.
- After that, reinstall Word from the App Store.
- Open Word and sign in again if prompted.
If Word Still Will Not Open
If both fixes fail, the issue may be tied to your device rather than Word itself. Check whether other Microsoft apps open normally, and confirm that your iPhone or iPad has enough free storage space. If the problem affects only Word and keeps returning after reinstalling, the app may need another update from Microsoft.
- Make sure iOS or iPadOS is updated.
- Check that the device has enough free storage.
- Try opening Word while connected to a stable internet connection.
- If Word crashes only on one account, sign out and sign back in.
