What is One Drive Mac Container?
This container belongs to Microsoft OneDrive on macOS. App containers under ~/Library/Containers are used by sandboxed apps to store data such as settings, account state, local app files, and other information the app needs to run. People usually encounter this folder when reviewing storage use, troubleshooting OneDrive behavior, or removing OneDrive from a Mac.

Safety overview
Status: Mostly safe
This is not a system folder, but it may contain OneDrive data needed for the app to launch properly, remember sign-in status, or keep local sync-related settings. Deleting it while OneDrive is installed can reset app state or require you to sign in again, and may affect locally stored OneDrive data on the Mac until the app rebuilds its files.
Recommendation: Keep this folder if you still use Microsoft OneDrive. If OneDrive has been fully uninstalled and you no longer need its local app data on this Mac, this container is usually optional to keep. Review whether you still rely on OneDrive offline files or local settings before removing it.
