I am using Office 2013, and I am on Windows 8.1 with OneDrive setup. I keep some files Offline and OneDrive syncs it for me which is cool. But when I installed Office 2013, when I edit Excel files, I notice that there's an Uploading to OneDrive message at the bottom while saving. Then I was prompted with a conflict during the sync. Isn't this because OneDrive is already syncing it and Excel is syncing it again that's why this happening?

How do I disable Excel (or probably Word as well and other apps in Office) to stop saving directly to OneDrive? How do I disable the Office Upload Center that keeps on popping in the System Tray? I am already fine with the sync being done by the OneDrive Desktop. Previously, there was an option to disable Office sync from the OneDrive Desktop icon in the System Tray, but it is now gone and I couldn't find it anywhere else. Where do I find it now?

To disable/configure this open up the Task Scheduler and click on the Task Scheduler Library node. You should see a task here labelled Microsoft Office 15 Sync Maintenance for USERNAME.

Disable the whole trigger (right click and choose disable) or change the Properties of this to amend the trigger that starts the job. For instance, you can delete the trigger that starts on user log on.

The other way is to find MSOSYNC.EXE and OSPPSVC.EXE on Disk C:, delete them:

1. Open task manager and kill MSOSYNC.EXE and OSPPSVC.EXE
2.  Search C: for MSOSYNC.EXE and note which one is the actual Office folder, then delete them all
3. Go to the Office folder and create a MSOSYNC.txt file and edit it to put the quit command in it.
4.  Rename the file to MSOSYNC.EXE and then change the permissions so the user owns it, and remove all permissions except for the user which should have all except WRITE.
5.  Reboot

This method above is like cheating, you can make fake MSOSYNC.EXE and OSPPSVC.EXE so that they can't even run.

Anyway, Microsoft doesn't recommend you disable the Upload center.

Thanks for your reply Jeff. I have done options 1 and 2. I didn't encounter any conflicts yet, but there's still Uploading to OneDrive message at the bottom part of Excel. Although I don't know if its actually doing anything since I renamed the files.

I do hope they bring back the setting in OneDrive Desktop to turn off the Office sync when OneDrive is already doing the same thing. I am not comfortable with the changes I did. I'm sure there are a number of people doing the same thing that I am doing and would experience the conflicts.

Spoke too soon. I encountered the conflicts again. This is frustrating.

English version:

1 - Right Click on the OneDrive tray icon > "settings".

2 - Uncheck "Use Office to sync files faster and work on files with other people at the same time."

3 - Reboot computer.

Version franaise :

1 - Clic droit sur l'icone OnDrive > "Paramtres".

2 - Dcocher la case "Utiliser Office pour travailler sur des fichiers en mme temps que d'autres utilisateurs".

3 - Redmarrer l'ordinateur.
