Symptoms

Using a Cached Mode profile, in Microsoft Outlook you see the following error in messages with the subject Synchronization Log in the Sync Issues folder:

Terminated in error
[80040600-501-80040600-560]
The client operation failed.

This error may appear alone, or accompany other actions or conditions, such as Send/Receive, missing email, or slow synchronization with Exchange Server.

Cause

This error has been associated with Outlook Data File (OST) corruption. The cause of corruption has never been determined.

Resolution

The error may be resolved in Outlook 2016, Outlook 2013 or Outlook 2007 by deleting and recreating the Outlook Cached Mode OST file. If that fails, then creating a new Outlook profile will resolve the issue.
