微软官方 2024年8月15日 的更新支持文档，承认包括 Outlook、Word、OneNote 在内的 Office 应用存在 BUG，用户在输入、检查拼写或者或执行其他编写任务和操作时可能会遇到崩溃情况。
微软表示 Office Version 2407，Build 17830.20138 以及后续版本均存在上述问题，在事件日志查看器中会记录为 Event 1000 或者 Event 1001。
支持文档中，微软表示之所以出现上述问题，其根源可能在于语言包过时：
如果语言包版本没有更新到当前版本，可能会出现这个问题。
用户可以检查 C:\Program Files\Microsoft Officeoot\Office16\mscss7xx.dll 的版本，理论上版本号应该是与 Office 版本密切匹配，但可能出现不完全匹配的情况。
Outlook, Word, or OneNote unexpectedly close when typing
Excel for Microsoft 365 Word for Microsoft 365 Outlook for Microsoft 365 PowerPoint for Microsoft 365 OneNote for Microsoft 365 Less
Last Updated: August 15, 2024
ISSUE
After updating to Version 2407 Build 17830.20138 or higher you find that Outlook, Word, or OneNote may unexpectedly close when typing or doing other authoring tasks such as spell check.
You can confirm if this is the issue by looking at the Windows Event Viewer Application Log for Event 1000 or Event 1001, and the following event details:
Faulting application name: OUTLOOK.EXE, version: 16.0.17830.20138, time stamp: 0x66aaad8c
Faulting module name: mscss7it.dll, version: 16.0.12527.20122, time stamp: 0x5e439ea1 Exception code: 0xc0000005
Fault offset: 0x000000000003e518
Faulting process id: 0x0x51B0
Faulting application start time: 0x0x1DAE97DD89190C3
Faulting application name: OUTLOOK.EXE, version: 16.0.17830.20166, time stamp: 0x66b7aa44
Faulting module name: mscss7ge.dll, version: 16.0.4288.1000, time stamp: 0x55f830b9
Exception code: 0xc0000005
Fault offset: 0x0000000000031991
Faulting process id: 0x0x506C
Faulting application start time: 0x0x1DAEE7B92076D82
The faulting module name will vary depending on what language packs you have installed. For example, mscss7it.dll for Italian, or mscss7ge.dll, for German, and others could include: EN, ES, FR, GE, IT, NP, PB.
This issue may occur if the language pack version is not updated to the current version. If you check the version of the C:\Program Files\Microsoft Office\root\Office16\ mscss7xx.dll it should be a build closely matching the Office version but might not match exactly.
STATUS: WORKAROUND
The Outlook and Office Teams are investigating the issue.
To work around the issue, do the following:
Do an online repair of the Office application, Repair an Office application.
If the event log event shows the faulting module with a version such as 16.0.4288.1000 then this means you have an older MSI version of the language installed. Go to Windows Settings > Apps > Installed Apps and look for the old Office language installation and uninstall it.
Uninstall and reinstall the language pack, see “Step 2: Configure Microsoft 365 language”, Language Accessory Pack for Microsoft 365.
