Tue Sep 17 06:32:01 UTC 2024: ## Microsoft Fixes Office App Crashing Issue Caused by Outdated Language Packs

**Redmond, WA – September 17, 2024** – Microsoft has finally addressed the issue that caused Office apps like Outlook, Word, and OneNote to crash when typing or spell-checking. The problem stemmed from compatibility conflicts arising from outdated language packs, as the company explained in August.

Initially, Microsoft offered a temporary workaround, but now they’ve released a permanent fix. The company states the issue was caused by a “version mismatch between Office 2016 proofing tools and Office language packs (M365 apps for Enterprise)”. This mismatch typically occurs when older proofing tools, leftover from previous installations or migrations, are used alongside newer Office versions.

This issue is now resolved in the following Office builds:

* **Beta Channel:** Version 2409 (Build 18021.15000)
* **Current Channel Preview:** Version 2409 (Build 18025.20000)
* **Current Channel:** Version 2409 (Build 18025.20000) (Expected release: September 24th)

Microsoft emphasizes that users should update their Office applications to these builds to prevent future crashes.

The fix addresses two specific issues:

1. **Older proofing tools installed with M365 Office:** Users should uninstall any Office 2016 proofing tools if they are using a later version of Office and install the appropriate Office language packs instead. These language packs update automatically along with the version of Office.
2. **Mismatched language pack versions:** The fix also prevents crashes that occur when the M365 Click to Run language pack version is different from the main installer version.

If you are still experiencing crashes after updating to the fixed builds, Microsoft recommends repairing your Office installation using the workaround guidance available on their website.

Microsoft assures users that this fix will prevent future occurrences of the crash issue.
