Upload center cache error

FIX: An error occurred while accessing the Office Document Cache

“Microsoft office upload center found a problem while accessing the Microsoft office document cache” the basics.

It may happen that when you upload a Microsoft Office file you receive an error message that your Microsoft Upload Center has an error with the Office Document Cache. The Upload Center indicates in the error message that you can try to restart the Upload Center, and if the error message keeps coming back you can completely remove the Cache. Personally, I never delete the cache directly. I move it so that I can always put it back if problems arise.

Below the error message is a short manual with screenshots that describes how you can solve this problem.

  1. It usually fixes the issue for the first time after reboot, but the error is occurring again even after a new folder of OfficeFileCache is recreated. What should be done?
    Should I go ahead and delete the old folder and retry?

    Also, i did not find any msouc.exe running in task manager, hence i skipped that part. Any suggestions??

  2. This worked – the MSFT help tells you to use the Settings dialog in the Upload Center app, but apparently things were so screwed up that it couldn’t even launch that – it would just hang. So I killed MSOSYNC (the name for the upload app) using Task Manager, and then deleted the files in %userprofile%\AppData\Local\Microsoft\Office\16.0 (note it is 16.0 for Office 2016) – for me, these were named OfficeFileCacheN where N was 3, 4, etc. I just nuked all of them and then it worked.

  3. Hi, I have a problem with upload center, it says Upload Pending. When we upload to the cloud it happends, but on our own network we do not have a problem. But this is really annoying because when your upload is pending and someone else opens the file, and then he saves it. the other person did not get the changes from the other user. It doesn’t happen to all the files. Is it maybe a problem because the people open up a file at the same time? I didn’t think that was possible..

  4. I came through step 5. But the file you mentioned by step 6 I couldn’t find it. I work in Windows 10. Do you know where it is? I have the issue with Office 365 by using One drive.

    1. Hi,
      Maybe this will solve your problem.
      You need to enable the hidden files and maps in control panel and then map options.

      Regards

      1. sorry its called file explorer options in cdontrol panel, choose view tab and click the radio button in the list : view hidden files, …

  5. I can’t find the file you named by step 6 in Windows 10. Do you know where it is? I have the issue with Office 365 by using One drive.

    1. Look at %userprofile%\AppData\Local\Microsoft\Office\16.0 and look for OfficeFileCacheN where N is a number. He calls it OfficeFileName but that is a typo in the post – it is OfficeFileCache.

  6. Hi Bas
    Thanks for your guideline. I tried those steps one by one twice but the problem still occurs.
    I’m using Office 365 & onedrive for business from my university.
    The office upload center in the tray icon always says “file failed to upload”
    Is there maybe something that I missed?

    Regards
