OneDrive for Business sync client issue - not finishing
Hi all,
I’m experiencing an issue where OneDrive does not finish synchronizing. It runs for about an hour. Upload is not starting until download worked fine.
Everything seems to set up correctly:
- Internet connection is working
- No large file involved (9,9 MB of 10,3 MB)
- Logged in sucessfully
- Free space available loacally and in OneDrive
- No sync conflicts
- E3 License is active and paid
- No Windows updates Pending (Windows 11, version 24H2)
Tried solutions:
- Restarted OneDrive
- Restarted Windows
- Paused and resumed sync
- Stopped and restarted sync
What i am wondering:
- My local OneDrive version is not listed in the https://support.microsoft.com/de-de/office/onedrive-versionshinweise-845dcf18-f921-435e-bf28-4e24b95e5fc0 ....
- How can I identify the specific file causing the issue? I don’t see the filename currently being processed.
Help highly appreciated :-)
Regards,
Eric
Thanks for your suggestions! Itried the manual way.
I searched for folders in the Windows File explorer with pending synchronisation status.
I identified each pending file, moved it to a separate Folder and uploaded via drag and drop via the webbrowser to its destination.
It was about 100 files (luckx me) and took me about an hour. Now it works again, but i still do not know the cause.
Searching the logs would be great i opened this folder and ask myself how to read the logs?
%localappdata%\Microsoft\OneDrive\logs
There are with editor unreadable file types as aodl, etlgz, loggz, odl, odlgz.
SyncDiagnostics.log could be a nice source, but it shows only the current status. As my issue is resolved, the cuase of the problem is not listed anymore.

Hey Eric,
It sounds frustrating! A few things you can try to identify the file causing the sync hang:
Check the OneDrive Activity Center – click the OneDrive icon in the taskbar and see if it shows “Processing [filename]” or any stalled files.
Use the OneDrive logs – press Ctrl + Alt + F in the OneDrive client to generate a log file; it often lists the last files being synced.
Move small batches – try moving small groups of files out of your OneDrive folder temporarily to see which batch triggers the hang.
Check for hidden/system files – sometimes hidden temp or system files can block sync.
Also, make sure your OneDrive client is up to date; older versions can cause issues not listed in the version notes.
Hopefully this helps you pinpoint the problem!
Hi Eric,
This usually happens when OneDrive is stuck on a hidden or locked file. You can check this by clicking the OneDrive icon → Settings → Sync → View sync problems. Also try opening OneDrive logs (%localappdata%\Microsoft\OneDrive\logs) — the SyncDiagnostics.log often shows the exact file name.If your client version isn’t listed, updating to the latest OneDrive build manually from Microsoft’s site can also resolve it.
Hope this helps
Can anyone help? Still not working ... did not resolve by itsself?
