We use 7.1.4 with the OL connector (OL2010/32-bit). When I delete an email in OL and then at a later time go offline, the deleted emails in OL are still present in the Zimbra inbox.

When I then open my Zimbra account via normal IMAP from a mobile device and delete the emails, these are then gone instantly in my Zimbra account too.

What do I need to do to make sure that emails deleted in OL are deleted in Zimbra too?
