When faced with a problem like this, your primary approach should be to identify the file size of the executable files, check the file location, and verify whether the process poses a security threat. Keep reading to find these aspects about msosync.exe!
What is msosync.exe, and what is its functionality?
The process, msosync.exe, is linked to Microsoft Office and is primarily responsible for cache management. Its job is to ensure that users can quickly access Excel, Word, PowerPoint, and OneDrive files.
The software component does so by actively running in the background, collecting the required data, and creating a cache such that the file, when opened, quickly shows up, thus eliminating any extended loading period and ensuring faster viewing.
The original file path for msosync.exe is (Xrepresents the version of Microsoft Office):C:\Program Files\Microsoft Office\OfficeX
But the file, with an exe file extension, has often been a source of a wide range of problems. For some users, it triggered error messages, a few found thatMicrosoft Word was not working, while others reported msosync.exehigh CPU usage.

Ideally, you shouldn’t remove or disable msosync.exe in Windows. But if the process takes up a high CPU or there’s a corrupt file version, that could be a solution.

If none helped, move to the wide range of fixes listed next.
1. Rename the msosync.exe file
Once done, restart the computer for the changes to come into effect, and you shouldn’t face issues with the corrupt files anymore. By renaming the file, you prevent Microsoft Office from accessing it.
2. Kill the task in Task Scheduler
Many users found that the process was triggered by a sync task, and disabling it completely stopped msosync.exe. You may not find the task on a newer file version.
3. Download the missing DLL file
If you are facing an issue due to a missing DLL or file loss, it’s wise to download the missing DLL. While several websites claim to host DLLs, we recommend against these.
It’s best to either get the applicable version of the DLL from another PC running Windows or use aneffective DLL repair software. The latter should be the preferred approach, given that it’s automatic and most tools have a vast database comprising every DLL out there.
4. Repair Microsoft Office
Make sure you are connected to the Internet before starting an online repair of Microsoft Office since it would download a wide range of files, both corrupt files and one critical to the functioning.

Also, uninstalling won’t affect the files stored on the cloud service, and you candownload OneDrive from the Microsoft Store.
How do I remove msosync.exe?
