Files on Demand - The Cloud sync engine failed to validate the download - Error 0x8007017F
Hi,
I have a customer whom we've recently turned on 'Files On Demand' (version 17.3.7076.1026 - most recent version). Intermittently when they open file's from Sharepoint (Via One Drive Files on Demand), they receive the below error (screenshot below)
Error 0x8007017F: The Cloud sync engine failed to validate the downloaded data.
Any ideas how we can resolve or why we are getting the above error?
Thanks
Michael

Hi,
I recently tried to backup files from OneDrive to a Computer and has the same error appear. I turned off Files On Demand by right-clicking the OneDrive menu at the bottom right of your screen, going to setting, click on the settings tab and then turn off "Save space and download files as you use them". This will download all the files to your PC and you shouldn't have issues copying the files to different locations. After that, turn Files on Demand back on. I know it isn't a good solution to give to end users, but at least it works.
Hope this helps, sorry if it didn't.
I had this exact same error message. Fortunately in my case I was able to swiftly fix it by closing the OneDrive app and reopening.
- Same problem here. Found a jerryrig though: I dowloaded the file from the onedrive via my browser. Then deleted it from the folder, reuploaded it to onedrive by dragging and dropping it in the folder from the OneDrive desktop interface, seems to work for now.
Just saw the same issue at a client. Try Again doesn't seem to do anything but if they click Skip the file opens right away.
We are experiencing the same error at our company. Anyone with a solution to this problem?
- Typical Microsoft - there'll be a load of bugs but bugger all the customers tying to use it
I'm having the same issue with a client. I removed the files on demand then readded. Waiting to see if that worked.
- Hey. Any progress on this issue? I have same error for a new Doc Library seems to be effecting all users.
- Yes, I had the same problem today trying to copy files from OneDrive to backup on a thumb drive; however, I got around it. I had to change the setting on OneDrive to share files. Right Click that drive, go to Properties, slick the Sharing tab and follow the instructions.
However, this does not like to copy entire folders unless they are empty, but you can select all files to copy at once (in a folder) to paste where you want.
Hope this helps.
HI has anyone a solution to this issue????
I have an ongoing ticket with Microsoft on this. Several attempts at fixing have been made with unreleased versions of OneDrive. No dice.
Similar issues here albeit with error code 0x80070185. Heard about any fixes yet?
Does anyone have an update on this yet? We have about 6 users using Files On-Demand and 2 are experiencing this and the others are not. The two that are are syncing the same libraries. The other 4 are not. So maybe an issue with the library?
I was able to reproduce this when a file was being edited on two PC's at the same time. Onedrive renamed the file on one computer, adding the computer name to the filename. The computer on which the file was renamed is now unable to sync the original file name (even though I deleted the renamed file).
I was able to resolve this by
- taking a copy of the file on the computer without the problem (saving out of OneDrive alltogether)
- delete the original file on the computer not reporting the error
- moving the copy to OneDrive in place of the file just deleted
just make it stay ,and it will be no error
