Windows 10: Thumbnail previews do not appear in OneDrive folders

(Can't seem to post this to OneDrive so reverting to Windows)


My Documents on my machine is configured in my OneDrive folder system. All data is saved in OneDrive and then synchronized to the Cloud. Several months ago, I lost the ability to "reliably" see Thumbnail previews of images in my picture folders. Rather than seeing a thumbnail of the picture, all I see are icons. In a folder that may contain 100 picture files, there may be 5 or 10 thumbnails... The rest show a standard icon. I have tried every trouble shooting method shared on the net and from Microsoft. I just spent several hours working with the Windows 10 support team first with a junior tech and then with a senior tech and we isolated the problem to an issue with OneDrive where thumbnails do not seem to synch properly.


Example...

1. If I copy all the pictures from one of my OneDrive folders to a folder on my desktop all the thumbnails appear without an issue.
2. If I create a new folder in OneDrive and copy the same pictures to that new folder the thumbnails appear at first... If I close the folder and reopen it, the thumbnails disappear.
3. In working with the senior Windows tech we copied all my picture files from my OneDrive folder to a new folder on my desktop. Again all thumbnails worked correctly. After verifying that we had copied all files we deleted the pictures in OneDrive so the folder was empty. We then copied the pictures that were now in a folder on my desktop to OneDrive. Similar to #2 above, at first it appeared as everything worked correctly but when I closed the OneDrive folder and opened it again, the thumbnails disappeared.

Preview Pane for Images/Some Thumbnails/Photos not Working Only on OneDrive Folder

The preview pane and thumbnails as well as the Photos app are not working, but only on my OneDrive folder. It works fine on an exact copy of the same files that are not in the OneDrive synced folder structure (and known to Windows as being OneDrive).

• Open OneDrive Folder, navigate to photos directory
• Sony Raw images (.ARW) do not show thumbnails. (I have the Sony plug in installed)
• Double click on a raw file, Photos says "We can't open this file."
• Click on a jpeg file, and with preview window turned on, no preview appears
• Double click on jpeg file, opens fine in Photos, and then the preview window image appears

• Navigate to a directory that is not synced to OneDrive
• Sony Raw thumbnails show up fine. They also show up in the preview window.
• Double click on Raw file and Photos opens it up without problems

• Back to OneDrive photo directory
• Copy raw file to desktop
• Immediately the thumbnail appears and the file can be opened with Photos. The same file that it can't open from Explorer in the OneDrive directory

This is only happening on my desktop. My laptop is fine. Both same versions of Windows 10 Version 1709 OS Build 16299.19

Preview Pane for Images/Some Thumbnails/Photos not Working Only on OneDrive Folder

Thanks for the suggestion. I uninstalled and re-installed OneDrive but the problem persists.

I just copied a Raw file to the desktop from OneDrive and the thumbnail appeared on both the desktop copy and the original. Strange.
