Hi there,
Please see responses below:
Does the error message only appear when you move a specific document to a folder in SharePoint site: No it can happen with any type of documents
I suggest you try following:
1.Clear the browser cache or use the private window of the browser, or try using different browsers such as Edge, Chrome, Firefox, then test again. Tried 2 browsers but it happens with both Chrome and Explorer. Note if users back out and or refresh it does not happen and the folder list****appears
2.Move the folder to different folder and see if issue only happens when you use that folder as the destination folder.
This issue h appens within other folders not just one on the SPO site
If issue persists, I'd like to confirm information below to help you do further troubleshooting. Thanks for your time and effort.
1.If you move a different document to folder, does the error message appear? Yes as it is not happening to only 1 folder or just 1 user
2.Where is the folder? In the same SharePoint site or a different SharePoint site? Folders are all within the same SPO site
Appreciate your assistance with this matter as it is affect a few users.
Thanks
te
3.Please share a screenshot of the error message
