I have a work email account that uses Zimbra as the backend server. For my iDevices, I set up this account as an exchange account and everything usually works fine. On my laptop, it's set up as IMAP (for some reason I can't set it up as exchange there).
My problem is that when I read mail on my MacBook and move it to another mailbox, it doesn't always update the inbox of the iPad. My iPhone seems to be fine though. I'm seeing old mail still in the inbox even after I slide down the message list to "refresh". Any ideas?
