Resolve App Lag and Freezes: If the temporary files become too large or corrupted, they can cause Office programs to stutter, freeze, or crash entirely upon opening.
Free Up Disk Space: Frustrated by the 100 disk usage Windows 11 issue? Your massive Excel spreadsheets or PowerPoint presentations with high-resolution graphics may consume valuable storage space on your hard drive.

Before deleting any temporary files, make sure Word, Excel, and PowerPoint are completely shut down.
Right-click the app icons in your Dock and select Quit (or press Command + Q while inside the app).
Open Finder > Click on Go in the top menu bar, then select “Go to Folder”.
In the "Go to Folder" search bar, type or paste the following path and press Enter:
~/Library/Containers/
Scroll through the list to find the Microsoft folders. Depending on your version of macOS, they will look like this:
com.microsoft.Word
com.microsoft.Excel
com.microsoft.Powerpoint
Open the target folder, navigate to Data > Library > Caches, and delete the contents of that folder.
You don’t need to do this regularly. Only clear Office cache when you are actively experiencing troubleshooting issues, such as file syncing errors, constant "Upload Failed" warnings, or application lags.
No, it will not delete your saved local or cloud documents. However, if you have a file with unsaved changes that is currently stuck uploading to the cloud, those specific unsaved edits could be lost. Ensure you've saved essential data before you clear the cache.
