A Microsoft file hosting and synchronization service.
HiSteph1989YU,
Greetings!
Thank you for posting in Microsoft Community.
Based on the description you posted, it seems that you have an issue with MS Office wherein you want to know how you can remove your OneDrive personal files on your work computer.
Let’s work together in finding the best solution to this issue.
In the meantime, we would like you to try the steps provided down below:
Step 1: Choose which OneDrive folders to sync to your computer
Open OneDrive settings (select the OneDrive cloud icon in your notification area, and then select the OneDrive Help and Settings icon then Settings.)
- Go to the Account tab.
- Select Choose folders.
In the Sync your OneDrive files to this PC dialog box, uncheck any folders you don't want to sync to your computer and select OK.
**Note:**You cannot add non-OneDrive folders (such as C: and D:).
Notes:
- If you uncheck a folder you are syncing to your computer, the folder will be removed from your computer. The folder and its contents will still be available online.
- The sync settings you choose are unique to each computer unless you're syncing everything everywhere. Also, if you're choosing folders on two computers and you create a new folder on computer A that you want to sync to computer B, you'll need to go to computer B and select the new folder there.

Steps 2: If you made a mistake adding or uploading the file to your OneDrive folders
- Pause OneDrive.
- Delete it or move it out of your OneDrive folders. **Tip:**Files deleted from OneDrive.com go to your OneDrive recycle bin. Files deleted from your computer's OneDrive go to your computers Recycle Bin or Trash.
- Select the OneDrive icon on the taskbar or menu bar and select Resume
