On couple of users mailbox in outlook i can see a folder by name Sync Issues under sync issues it has a folder by name conflicts,Local Failures sync issue has 10,000 mails, conflicts has 5000 mails. How do i clear these emails from server side, and also i am not able to clear them from outlook as i am getting error
Can you delete them from OWA? It may help if you can provide details about the error message you are receiving if that doesn't work. Also, I would recommend reviewing the sync issues and resolving whatever is causing them.
