Hello, you’re using an outdated version of eM Client, please try to update your eM Client to this release, 6.0.22774.0 and check if the issue persists. If it does, please try to perform a folder repair on folders that seem to be causing the problem during sync - right click the folder in the left pane and select Properties > Repair and click on the Repair button, this will essentially re-sync the folder with the server.

Hope this helps,
