StandaloneUpdater User Caches
This folder stores cached updater data used by StandaloneUpdater for Microsoft OneDrive update checks and installation tasks on Mac.
What is StandaloneUpdater User Caches?
~/Library/Caches/com.microsoft.OneDriveStandaloneUpdater is a user cache folder created for StandaloneUpdater, the updater component associated with Microsoft OneDrive on Mac. Cache folders like this store temporary data that helps the updater download, verify, stage, or resume update-related work more efficiently. Users typically encounter it while reviewing storage use, clearing cache files, or removing leftover app data during cleanup. Deleting this folder usually does not remove OneDrive itself, but it can clear temporary updater data and may cause the updater to recreate the folder later when OneDrive checks for or installs updates. This is a normal part of app maintenance data rather than a document or settings folder.

Safety overview
Status: Mostly safe
This folder contains temporary updater cache data, not the main OneDrive app or your personal documents. Removing it is generally low risk, but any in-progress or recently downloaded update data may be discarded, and the folder may return the next time OneDrive updates itself. If OneDrive is updating right now, wait until that finishes before deleting the cache.
Recommendation: You can delete this folder if you want to free a small amount of space or clear temporary updater data. Keep it if you use OneDrive regularly and do not have a reason to troubleshoot updates, since the app may simply recreate the cache during normal use.
