Upload Failed: Your file was not uploaded because your changes can not be merged with changes made by someone else error for Excel and PowerPoint in MS Office 1903 build RRS feed

  • Question

  • Hi,

    We have office integration implemented in our application using Office URI Schemes for editing server files.

    For Example: ms-excel:ofe|u|https://path_to_file  for editing the server office files.

    Steps: i) We form the above webdav URL

               ii) Handover the URL to OS to open the corresponding office application.

               iii) Make changes in office files and then save it which saves the changes to server.

    Problem: We have our user facing issue while checking in any office files(saving to server) i.e, user is facing issue while saving the modified office file after checking it out.

    The file opens in "Protected View", user clicks on "Enable Editing". Then user modifies the file and clicks on Save.

                     > For Excel an error message "Upload Failed: Your file wasn't uploaded because your changes can't be merged with changes made by someone else" pops for excel.

                    > And for PowerPoint an error message "Save Again: We need to refresh your file with updates.Click save to try again."

    We have performed "office Upload Center" cleanup activity and also office repair following the blog . But still face the issue. 

    Note: 1) The same works for MSO Excel 1808 build version but not in 1903 build which the user is using.

             2) File is not shared with any other user( mentioning this as we came across that co-authoring may cause this issue)   

                3) Once the user clicks on "Discard Changes"  and modifies again , then the file saves properly. But yet this will be a workaround but not a permanent fix   

    Kindly suggest if we are missing anything from application end or any changes that we need to incorporate ?

    Thanks In Advance

  • Hi,
    we have the same problem.
    Office 2016 Win10 1903 Build: 18362.207

    Office documents can be opened and edited in the webdav. When saving, the upload center will fail to upload
    An upload error is displayed.

    This error does not occur with Win10 1809.

  • Same problem here.

    We have SharePoint 2016 (onpremise) and Office 2016 and we have only problems with files which are opened directly in excel (webdav, libraries which open files directly in client app, and special Excel files which cannot be opened in office online).

    If the file gets opened through "Office Online" there is no problem.

    We have Windows 10 1809 and it still does NOT work!

    Clearing the cache and disabling the antivirus also does not help.

    Is someone working on that?

  • Uninstalling the Security Update for Microsoft Office 2016 (KB4475591) solved our problem.
    Office 2016 will work with Win 10 1903 or 1809

  • Yes, it is a workaround.
    If you for security reasons you can not uninstall this update (like us), another workaround is to change the Upload Center Settings and check the setting "Delete files from the Office Document Cache when they are closed". This has the disadvantage, that offline working is not working properly anymore.

    We have an open support ticket with microsoft and they working on an update which will fix this issue.
    They said this update should come this or next month.

    As soon as I get the info from microsoft, that the new update is out, I will let you know.

  • We also got the info from Microsoft that KB3085368 should fix the issues.

    In my first tests everything looks good again.
