If your computer crashes every time you try to use Outlook, Word, or OneNote, it looks like you’re not alone. Microsoft has just confirmed that a bug has been found that can cause this software to “quit unexpectedly”. The issues seem to have plagued some users after upgrading to Windows version 2407 Build 17830.20138 or later, with the crash occurring when typing or performing other authoring tasks such as spell checking.
It’s unclear how many users have been affected, but Microsoft has issued an official notification of the bug and says it’s working on a fix.
“Outlook, Word, or OneNote closes unexpectedly while writing,” the Redmond company announced.
“After upgrading to version 2407 build 17830.20138 or later, you may notice that Outlook, Word, or OneNote may close unexpectedly while typing or performing other authoring tasks, such as spell checking.”
To confirm that your computer is affected, Microsoft says you should check the Windows Event Viewer application log for event 1000 or event 1001 and the following event information:
• Faulting application name: OUTLOOK.EXE, version: 16.0.17830.20138, timestamp: 0x66aaad8c
• Faulting module name: mscss7it.dll, version: 16.0.12527.20122, timestamp: 0x5e439ea1 Exception code: 0xc0000005
• Bug fix: 0x000000000003e518
• Bad process ID: 0x0x51B0
• Faulty application start time: 0x0x1DAE97DD89190C3
• Faulting application name: OUTLOOK.EXE, version: 16.0.17830.20166, timestamp: 0x66b7aa44
• Faulting module name: mscss7ge.dll, version: 16.0.4288.1000, timestamp: 0x55f830b9

• Bad process ID: 0x0x506C
• Faulty application start time: 0x0x1DAEE7B92076D82
It’s been confirmed that Microsoft’s Outlook and Office teams are looking into the issue, so hopefully a fix will be released soon, but in the meantime, there’s a workaround.
Microsoft says users can fix Office online. All information here – Fix Office application.
If the event log event shows a faulty module with a version like 16.0.4288.1000, that means you have an older MSI version of the language installed. Go to Windows Settings > Applications > Installed Applications and find the old Office language installation and remove it.
You can also remove the language pack and reinstall it, see “Step 2: Configure the language for Microsoft 365”, Language Accessory Pack for Microsoft 365.
Hopefully an official update will be released soon, but if your Outlook and Word documents keep crashing, this error is probably the cause.
