zimbra desktop is duplicating emails in my yahoo inbox. i receive pop ups of newly received emails which are the same as the older ones (everything including the time and date stamp is the same) and when I check my account online I can see only one copy of the email in the inbox. Happens quite regularly to generally the last two emails in the Inbox and is not one off. It is also filling up my online account with duplicates in all other folders too. Will have to uninstall zimbra unless this is resolved.
