My opened emails are syncing fine, but any unopened emails won't come through. If I use Outlook Web Access to open the mail, then it syncs, of it I open it via Outlook it will sync also. Any ideas what would be causing this?
I found this to be a problem with the anti-virus that was installed on the server. It needed to be configured for "proactive scanning". I found that if I manually scanned my mailbox then my iphone and android would receive the new, opened mail. After setting the anti-virus package to proactively scan, I am getting my new mail to my phones.
