You click the sync button. You wait. Nothing happens. Your files stay stuck, and that little cloud icon spins forever like it forgot what it was supposed to do. SharePoint sync issues can throw a wrench into your whole workday, especially when you need to access important documents right now.
This problem is super common, and the fixes are usually pretty simple. In this post, you will learn why SharePoint stops syncing, what causes these hiccups, and exactly how to get everything working again on your own.
What Does “SharePoint Not Syncing” Actually Mean?
When SharePoint syncs properly, it keeps a copy of your files on your computer that matches the files stored online. Think of it like two notebooks that should always have the same notes written in them. When syncing works, any change you make in one notebook automatically shows up in the other. But when syncing breaks, those notebooks stop talking to each other.
The sync process relies on the OneDrive app running in the background of your computer. This app acts like a messenger, constantly checking for changes and moving files back and forth between your computer and SharePoint online. When something interrupts this messenger, your files get stuck in limbo.
You might notice this problem in a few different ways:
- Files show a red X or cloud icon that never goes away
- Changes you made on your computer do not appear online
- Files edited by coworkers do not show up on your computer
- The OneDrive icon in your taskbar shows an error or keeps spinning
- You get pop-up messages saying sync is paused or stopped
Leaving this unfixed can cause real headaches. You might end up working on an old version of a file while your teammate works on a newer one. This leads to confusion, lost work, and sometimes having to redo things from scratch. Fixing sync issues quickly keeps everyone on the same page.
SharePoint Not Syncing: Common Causes
Before jumping into fixes, it helps to know why this happens in the first place. Understanding the cause often points you straight to the right solution.
1. Your Internet Connection Is Weak or Unstable
This one sounds obvious, but it catches people off guard more often than you would think. SharePoint needs a steady internet connection to move files around. If your Wi-Fi keeps dropping or your connection runs slow, the sync process stalls out.
Even a connection that seems fine for browsing websites might struggle with syncing large files or many files at once. The sync process needs consistent bandwidth, and any interruptions make it pause or fail entirely.
2. The OneDrive App Needs an Update or Has a Glitch
The OneDrive app handles all the syncing work behind the scenes. Like any software, it can get buggy, especially if it has not been updated in a while. Older versions sometimes have trouble communicating with newer versions of SharePoint online.
Sometimes the app just gets confused. It might be running but not actually doing anything useful. A stuck process or a minor software hiccup can freeze syncing without giving you any clear error message.
You might not even realize the app stopped working properly because it still appears in your taskbar looking normal.
3. File Name or Path Problems
SharePoint and OneDrive have rules about what you can name files and how long file paths can be. If a file name contains certain characters like # or % or if the total path length exceeds about 400 characters, syncing will fail for that file.
This problem often happens when someone renames a file or creates deeply nested folders without knowing the limits. The sync app tries to process the file, hits the rule violation, and gets stuck.
4. Storage Space Is Full
Your computer needs local storage space to hold the synced files. When your hard drive fills up, OneDrive cannot download new files or updates from SharePoint. The same goes for your SharePoint or OneDrive online storage. If your cloud storage quota is maxed out, new files have nowhere to go.
People often forget to check storage because it fills up slowly over time. One day everything works fine, and the next day sync stops because you finally hit the limit.
5. Credential or Sign-In Issues
SharePoint requires you to be signed in with the right account that has permission to access the files. If your login expires, your password changes, or your account loses access to the SharePoint site, syncing stops.
This happens a lot after IT makes changes to your company account or after you change your password. The OneDrive app might still show you as signed in even though the connection is broken.
Your company might also use security policies that require you to sign in again after a certain period. Missing these sign-in prompts leaves sync in a paused state.
SharePoint Not Syncing: DIY Fixes
Now that you know what typically goes wrong, let’s get your files syncing again. Try these fixes in order, starting with the simplest ones.
1. Check Your Internet Connection
Start here because it takes just a few seconds. Open a web browser and load a few different websites to make sure your internet works. Try watching a short video to test if your connection stays stable.
If your Wi-Fi seems shaky, try moving closer to your router or switching to a wired ethernet connection. You can also restart your router by unplugging it for 30 seconds and plugging it back in. Once your connection feels solid, give OneDrive a minute to catch up on syncing.
2. Restart the OneDrive App
Closing and reopening OneDrive fixes a surprising number of sync problems. The app sometimes needs a fresh start to clear out whatever was jamming it up.
Here is how to do it:
- Click the OneDrive cloud icon in your taskbar (bottom right corner of your screen)
- Click the gear icon for settings
- Select Pause syncing and then choose any time option
- Click the gear icon again and select Quit OneDrive
- Wait about 10 seconds
- Search for OneDrive in your Start menu and open it again
The app will restart and try syncing from scratch. Watch the icon for a few minutes to see if it starts showing progress.
3. Check for File Name and Path Issues
Look for files that show error icons or that never seem to finish syncing. Right-click on the OneDrive icon and look for any option that shows sync problems or files that could not sync.
Common fixes include:
- Renaming files to remove special characters like # % & * : < > ? / \ |
- Shortening file names that are very long
- Moving files out of deeply nested folders to reduce the total path length
- Avoiding file names that end with a space or period
After fixing any problem files, OneDrive usually picks up syncing automatically. If not, give the app a restart.
4. Free Up Storage Space
Check how much space you have left on your computer and in your SharePoint or OneDrive online storage. On Windows, you can see local storage by opening File Explorer, right-clicking on your main drive, and selecting Properties.
For online storage, go to SharePoint or OneDrive in your web browser, click the settings gear, and look for storage information. Delete files you no longer need or move them elsewhere to free up room. Even clearing out your computer’s recycle bin can help. Once you have breathing room, syncing should resume.
5. Sign Out and Sign Back In
This fix clears up credential problems that build up over time.
- Click the OneDrive icon in your taskbar
- Click the gear icon and select Settings
- Go to the Account tab
- Click Unlink this PC
- Confirm when prompted
After unlinking, open OneDrive again and sign in with your account. You will need to set up sync again, which means choosing which folders to sync. This process reconnects everything fresh and often fixes stubborn sync problems.
It takes a bit longer than the other fixes, but it clears out a lot of hidden issues at once.
6. Reset the OneDrive App
If nothing else works, resetting OneDrive gives it a completely clean slate without removing your files. This fix goes deeper than a simple restart.
Press the Windows key + R to open the Run dialog. Type this command and press Enter:
%localappdata%\Microsoft\OneDrive\onedrive.exe /reset
Your OneDrive icon will disappear for a minute or two. If it does not come back on its own after about five minutes, open the Start menu and launch OneDrive manually. You will need to sign in again and set up your sync preferences.
7. Contact Your IT Administrator
Sometimes the problem sits on the server side or involves settings that only your company’s IT team can change. If you tried all the fixes above and sync still fails, reach out to your IT administrator or help desk.
Let them know what you already tried. They can check if there are issues with your SharePoint site, your account permissions, or company-wide settings causing the problem. Some fixes require admin access that regular users simply do not have.
Wrapping Up
SharePoint sync issues feel frustrating, but most of them come down to simple causes like internet hiccups, app glitches, or storage limits. Working through the basic fixes usually gets files flowing again without much effort.
Keep your OneDrive app updated, watch your storage space, and pay attention to how you name your files. These small habits prevent most sync headaches before they start. And when something does go wrong, you now have a clear list of things to check and fix on your own.
