Push email is a wonderful thing when it works, and seemingly impossible to debug when it does not.
I'm using Zimbra 5.0.16 and iPhone 3GS & 3G with version 3 firmware. Zimbra mobile is enabled and the phones are configured to use exchange active sync.
Sometimes they work great, other times they dont. I can have the phone in my hand, connected to the wireless lan, in the same building as the zimbra server and a change made to the account on the web server does not reflect on the phone. They you try the same test another time and as soon as you delete a mail, it's instantly removed from the phone's screen.
I know the /opt/zimbra/sync.log will show the activity here but it I cant read it. Is there an easy way to diagnose these issues. Is there a way to ask zimbra what phones are connected to it?
