OneDrive for Business Sync Issues

Systems Involved:

Office 365


The issue started on Friday, November 13, 2015, at 11:43 AM UTC. As part of our efforts to improve service performance an update was deployed to the OneDrive for Business infrastructure; however, the update unexpectedly initiated the resynchronization process for document libraries. OneDrive for Business document libraries may resynchronize for no apparent reason. Some document libraries will resynchronize with no errors while others may receive the following error message: "An error occurred while attempting to synchronizing this document library."

Final Status: Engineers have confirmed that the service change successfully resolved the service side issue preventing any new users from becoming impacted. Previously affected users may be able to self-resolve the issue by following the steps outlined in this Microsoft Support article: . We are investigating on an update to the client to fix this issue and we will keep you updated with progress in the support article.

After further investigation, it was determined that the resynchronization being triggered by the product occurred as part of a by-design product change. However, during this process a code issue in the OneDrive for Business synchronization client application was revealed. Engineers are continuing to work toward deploying a fix on the service side to prevent further users from becoming impacted by this issue. In parallel, engineers are working on an update to the OneDrive for Business client application, which will resolve the underlying problem.

Problem Resolution: 

IT personnel are investigating the problem. No estimated time for correction of the problem is currently available. As a workaround for sync errors users should first try repairing the issue by right clicking on the OneDrive for Business icon in the systray and choosing repair. If that does not work then they should try the steps outlined in
