If there’s a specific file that isn’t synchronizing (red “x” on the file icon in File Explorer instead of a green checkmark or blue sync symbol), you can try duplicating the file in it’s current location by copy-and-pasting. Un-pause this to allow the flow of data again. It seems strange that there are two separate applications that manage the upload of documents, but I have encountered in the past where this application is paused, and it stops the SharePoint sync from progressing. This icon is the Office Document Uploader. Next, you may see an orange icon in your system tray. This action will force SharePoint to re-examine the files it needs to synchronize. Then resume the sync, and let it try to resolve itself. The first thing you should try is right-clicking the OneDrive for Business system tray icon, and pausing the sync. But long filenames, too large files, too many items, etc. The most common culprit is the “#” symbol in a file name, which is a no-no in SharePoint Online. The first thing to check is that you’re not accidentally violating SharePoint’s limitations. Here are some steps I usually take to try to resolve the issues. Right clicking on this icon will allow you to see the sync errors, which should list all the files that aren’t communicating properly. You’ll know if the sync is broken because the dark blue cloud icon in your system tray will have a red “x” on it. Maintaining that sync, however, is not as simple. SharePoint will then install the appropriate OneDrive for Business agent for your device, and download all the flies to your local machine and establish the ongoing sync. Simply navigate to the appropriate location in SharePoint Online, and click the big Sync link at the top of the screen. It's relatively easy to synchronize a Document Library with your PC. I’ll also finish it up by telling you about two solutions Microsoft is working on to make the entire experience much more robust and enterprise-friendly. In this post, I’ll wrap up the subject by giving you some possible troubleshooting solutions for resolving (almost inevitable) sync issues. In my previous two articles, I’ve discussed how to use SharePoint as a decentralized File Server for your organization, how to access the files once they’re there, and some of the advantages and disadvantages of the various methods.
