On a PC, you should see a white or blue OneDrive cloud icon in the notification area, at the far right of the taskbar.
You might need to click the Show hidden icons arrow 
next to the notification area to see the OneDrive icon.
If the icon doesn’t appear in the notification area, OneDrive might not be running. Select Start, type OneDrive in the search box, and then select OneDrive in the search results.
On a Mac, you’ll see the OneDrive cloud icons on the top Menu bar. If you don’t see the Menu bar, you may need to adjust your General preferences. For more information, go to Apple Support.
If the icon doesn’t appear in the Status menu area, OneDrive might not be running:

If you see this icon, it means your OneDrive storage is nearly full.
Caution: Your OneDrive account will be frozen if you exceed your OneDrive storage limit for more than three months.
To prevent going over your storage limit, you have three options:
-
Choose to buy more storage.
-
Delete some files and folders. View the largest files on your OneDrive.
-
Free up OneDrive storage by reducing what your sync. You can do this with Files on Demand or by choosing which OneDrive folders to sync with your computer.

Sign in to the OneDrive website and follow the on-screen instructions to unfreeze it.
