error message

Question

why does outlook and word keep giving in error message and instructing to close the app

Answer 1

Hi Secretary Bright Down

Thank you for your post. From your description, both Outlook and Word are showing an error and asking you to close the app, but it is not yet clear what the exact error says or whether both apps are failing in the same way.

Have you already tried the steps suggested in the Q&A Assist reply? If yes, please let me know:

• the exact error message shown in Outlook and Word
• whether both apps show the same message
• whether the apps close immediately or opens first and then shows the error

Before going further, it would help to confirm whether this is affecting Outlook or whether it appears to be happening more broadly across Office apps.

Meanwhile, please try a full Office repair, because Microsoft’s repair tool fixes the entire Office suite, not just one app. Official guide: Repair an Office application

Looking forward to your reply so I can assist you further. Thank you for your understanding.

Outlook and Word commonly show repeated error messages and close when there is a problem with the Office installation, language packs, or a known crash issue in a recent build.

For current Microsoft 365 versions, one known cause is outdated or mismatched language pack files (mscss7xx.dll). After updating to Version 2407 Build 17830.20138 or higher, Outlook or Word may unexpectedly close while typing or doing tasks like spell check. In Event Viewer this appears as Event 1000 or 1001 with a faulting module such as mscss7it.dll (Italian), mscss7ge.dll (German), or similar.

To fix the most common causes:

1. Run an Online Repair of Office
   • Open Windows Settings → Apps → Installed apps (or Apps & features).
   • Select Microsoft 365 or Microsoft Office → Modify → choose Online Repair and run it.
   • This repairs corrupted Office files and often stops the crash/error loop.
   • Reference steps: Repair an Office application.
2. Remove old MSI language packs (if Event Viewer shows mscss7xx.dll with an old version)
   • Open Windows Settings → Apps → Installed apps.
   • Look for any older Office language pack or language accessory entries (often MSI-based) and uninstall them.
3. Reinstall the language pack
   • Install the current Language Accessory Pack so its version matches the Office build. See “Step 2: Configure Microsoft 365 language” in Language Accessory Pack for Microsoft 365.
4. Make sure Office is fully updated
   • Open Word or Outlook.
   • Go to File → Account (or Office Account).
   • Under Product Information, choose Update Options → Update Now.

If the error text is specifically “We’re sorry, but Word has run into an error that is preventing it from working correctly. Word will need to be closed as a result. Would you like us to repair now?”, and the quick repair does not help, a full Online Repair or complete uninstall/reinstall of Office is recommended, as described above.

If crashes continue, check Windows Event Viewer (Application log) for Event 1000/1001 entries for OUTLOOK.EXE or WINWORD.EXE and compare the faulting module and version against the documented issue.
