Good morning gentlemen,
We're using Zimbra version 6.0.4_GA_2038.UBUNTU6_64.NETWORK 14 dec 2009, and a user reported a problem about duplicate emails in his sent items when he was cleaning up his mailbox.
He is not using the Zimbra connector for Outlook, he only logs on to Zimbra using the web client. If you take a look at the attached image, you can see that there are about 90.000 emails in his sent items, and you can see a lot of duplicate emails.
How is this possible, and how do I prevent this from happening?
