"An error occurred while attempting to synchronize this document library" error in OneDrive for Business

Problem

This article contains information that applies when you use the OneDrive for Business sync client (groove.exe).

NOTE: To determine which OneDrive sync client you're using, see the article, Which OneDrive sync client am I using?

When you use OneDrive for Business, you find that the program resynchronizes files, even when there is no apparent reason for the files to resync.

Also, when this problem occurs, some documents may generate the following error message during the resync process:
 

  • An error occurred while attempting to synchronize this document library.

Solution

The solution varies, depending on whether you’re running the Microsoft Installer (.msi) or Click-to-Run edition of Office. Be aware that the update on the Download Center that's mentioned later in this article applies to the Microsoft Installer (.msi)-based edition of Office 2013 and Office 2016. It doesn't apply to the Office 2013 or Office 2016 Click-to-Run editions, such as Microsoft Office 365 Home.

Note After you apply the update that's discussed in this section, your local libraries may show additional messages in the View Sync Problems dialog box, and these will have to be resolved. If you continue to experience errors after you apply the public update, right-click the OneDrive for Business cloud icon in the notification area, select View Sync Problems, and resolve any outstanding issues. If specific files or folders aren't syncing, try to move the affected files or folders out of the OneDrive for Business folder. Then, right-click the OneDrive for Business cloud icon, and select Sync Now. Then, move the files or folders back to their original location, and select Sync Now again.

You may have to remove the OneDrive for Business cache if the messages in the View Sync Problems dialog box can’t be resolved. For more information about how to do this, go to the article, How to remove the OneDrive for Business cache by using the "Easy fix" tool.

If you have the .MSI based edition of Office 2013 or Office 2016
