I’m an, Independent Advisor and Microsoft user like you and I'm glad to provide you information regarding your scenario.
Sorry to hear that you're facing issue with OneDrive upload.
Could you please let us know if you have done any password reset recently? If yes, all the other devices has to be refreshed to use the new credentials.
Also, if you're having trouble with your work computer, could you please check with the administrator to verify whether any option has been disabled to stop uploading files into OneDrive?
Also, if you logged in with the work account into the office files, you'll have trouble. Could you please logoff the work account from all the office apps and close all open applications. Kindly try following steps,
- In the Office app you're using (such as Word, Excel, or PowerPoint), click File.
