One Drive Says It is Sync'd but isn't

 Disconnecting and reconnecting as described below fixed this problem

 

 

Task Bar says up to date

 

 

 Windows file explorer shows not up to date.
PDF files do not seem to be going up

 

 

 

Looking at the web version and the non sync'd files definitely not there.

And checked we have plenty of free space.

Right click on the task bar and choose Settings

 I sent microsoft a note explaining the problem and I even gave them the link to this blog post.

THIS WORKED

---

1. Select the white or blue OneDrive cloud icon in the taskbar.

2. Select  Help & Settings then Settings.

3. On the Account tab, click Unlink this PC and then Unlink account.

4. Close OneDrive.

5. Press the Windows key + R to open the Run dialog.

6. Enter the path %localappdata%\Microsoft\OneDrive\settings and select OK.

7. Delete the PreSignInSettingsConfig.json file.

8. Press the Windows key   and type OneDrive.

9. When you sign in, OneDrive will prompt you that "a folder already exists" - select Use this folder.
   Tip: Select Choose new folder if you want to move your OneDrive to a new location, or if you were having sync issues.
   

10. OneDrive will now sync your files and folders back to your PC. OneDrive won't download all your files, (just their placeholders to save space,  learn more about Files on Demand below), but this will still take some time.

11. Once your files have re-synced, you can clean up your PC folder view and  choose which folders to sync to your PC.

This feels like a good thing.

Now we wait.....
