A Microsoft file hosting and synchronization service.
To stop emails and notifications related to OneDrive after turning it off, the practical option is to unlink or remove OneDrive from the computer and turn off its notifications. This stops sync activity and related alerts, while files remain available in the cloud if needed later.
On Windows 10/11:
- Select the OneDrive cloud icon in the notification area.
- Select the Help & Settings icon, then select Settings.
- Go to the Account tab.
- Select Unlink this PC, then Unlink account.
Optionally, to go further and remove OneDrive from the device:
- Open Settings to find the list of installed apps.
- Scroll to Microsoft OneDrive, select it, and choose Uninstall.
Unlinking or uninstalling does not delete files from OneDrive; they remain accessible anytime by signing in to OneDrive.com.
If emails are about storage being full or files being erased, they are triggered by the state of the OneDrive account (for example, exceeding storage or not using the account for a long time), not by the sync client on the PC. In that case, either:
- Sign in to OneDrive and manage storage (delete or move files) so it is no longer over quota, or
- Ignore the account if it is no longer needed, understanding that its contents may eventually be erased as described in the notification.
