Up until last week I just had a personal OneDrive folder and it had never worked properly in that it didn't update the backup. After taking some advice I decided to upgrade and purchase the Business Basic subscription in order I have a more reliable backup, but this is not syncing properly either. I have been trying for a week and have done everything I can think of including the unlinking then linking again, but it's still not working although the message in the blue cloud says all my files are synced. They are not. How do I get it to sync?

Thanks for all this, I actually ended up paying to have some expert help who has indeed really helped and I am up and running with everything synced, but I wouldn't have been able to do it without guidance.

    Dear @Vick, 

    Thank you for posting your question in the Microsoft Q&A forum. 

    To clarify, your Microsoft 365 Business Basic plan includes web and mobile apps. It doesn’t include the desktop Office apps by default, but OneDrive syncing and local file access are supported. 

    May I please confirm, your files are still not syncing, correct? 

    While I check further, could you try these quick general steps first: 

    Reset OneDrive 

    This refreshes the OneDrive app without deleting your files. 

    • Press Windows + R to open the Run dialog. 
    • Paste this command:  %localappdata%\Microsoft\OneDrive\onedrive.exe /reset 
    • Press Enter. 
    • OneDrive will reset and restart. 

    Reference: Reset OneDrive - Microsoft Support 

    Clear OneDrive Cache 

    This removes temporary files that may be causing the error. 

    • Quit OneDrive completely (via system tray or Task Manager). 
    • Open File Explorer (Windows + E). 
    • Navigate to:  %userprofile%\AppData\Local\Microsoft\OneDrive 
    • Open the log folder and delete all files inside. 
    • Restart OneDrive. 

    Update or Reinstall OneDrive 

    • Ensure you have the latest version of the OneDrive client. 
    • If needed, uninstall OneDrive completely and reinstall it from your account. 

    Verify file name & path limits: Avoid invalid characters; keep file names less than or equal to 128 characters and folder paths less than or equal to 250 characters. 

    Please kindly help me check your storage quota in OneDrive web. If OneDrive is full, syncing will stop.  

    Additionally, could you let me know which operating system you’re using (Windows 10/11)? If you’re on Windows 7/8/8.1, note that OneDrive desktop syncing support ended in 2022. OneDrive sync app no longer supported on Windows 7, 8 or 8.1

    If Personal OneDrive was not syncing properly before, then the possibility of the error coming from your laptop is very high, not just an account or subscription issue.

    Please kindly help me try these basic steps first and answer the questions. This will help me diagnose the root cause. 

    Looking forward to your reply!

    In my case, it was an attribute problem. Clicking on the Explorer folder -> Properties -> Attributes -> Hidden and i could finally see all files. So easy and evident, and I don't know why some of the files were hidden, but worth trying. I hope it helps
