I am an Exchange Administrator for a large University and have been managing Exchange Servers for well over 10 years. I just bought a new Samsung Note 3 (T-Mobile) and all of the sudden yesterday for some reason my phone will only sync old emails. Nothing since yesterday is showing on the device. I set up my same Exchange ActiveSync account on my wife's phone and it shows perfectly. I have not changed any settings, but there was a security update pushed to my phone a few days ago I had no power stop. I have verified ActiveSync is running smoothly on our Exchange server, I have removed the account, restarted the phone, and re-created the account from scratch on this Note 3. It still only downloads eMails since yesterday and older. The dozens of new eMails I have in my actual Inbox are all missing on my phone only. I can see them in OWA, Outlook and like stated earlier, even on another Samsung phone I tested with. What gives here? The phone has been working perfectly for the last 2 weeks as far as eMail goes, but now this.
