Microsoft has issues with Office apps that are causing problems for users

Microsoft is currently struggling with ongoing issues in its Office 365 suite that are causing trouble for users. According to Winfuture, many people have reported crashes and error messages in some Office applications, particularly Outlook, Word, and OneNote. The company is aware of the issues and is working to identify the root causes and provide a solution. One of the main issues is that Outlook users are encountering an error related to a missing file called “msls70.dll.” The issue first appeared in August 2024 and has recurred multiple times. Administrators have noticed that after updates, the issue disappears for a short time, but then reappears within a week. The error does not seem to have a clear pattern, making it difficult to fully resolve.

Crashes after deploying a new build

After the release of Microsoft 365 version 2407, build 17830.20138, users have reported more issues. These include crashes while typing, checking spelling, or performing other simple tasks. Word and OneNote users are also experiencing similar issues, making it difficult for them to work without interruptions. This has caused frustration among people who rely on these applications for everyday tasks.

Microsoft has acknowledged the ongoing issues and is investigating potential solutions. In a support update from almost two weeks ago, the company confirmed that the Outlook team is investigating the issue. However, a full fix is ​​still not available. For now, Microsoft suggests users switch to the new Outlook app or use the web version of the app as a workaround. Some critics, however, say that this is not an ideal solution for many users.

According to Microsoft, the issue may be due to incompatible versions of Microsoft Office proofing tools and language packs in Microsoft 365 apps. It appears that these outdated spelling tools were bypassed during upgrades from older versions of Office. These remaining tools conflict with newer versions, leading to crashes.

Microsoft has already started rolling out fixes through various channels. A permanent fix for the issue is expected to arrive on September 24, 2024 with the release of version 2409 (build 18025.20000). For users who have not updated to the latest builds, Microsoft recommends using the online repair feature in Office. In some cases, reinstalling language packs may be necessary to fully resolve the issue.
