Robert- first off my thought here has to do with wireless authentication on the iPhone. My understanding is that if an iPhone is connected to a wireless network that requires authentication (not a pre-shared key, but actual username/password, or even just an acknowledgement page, such as from Cisco lobby ambassador) that the phone will de-auth every time it goes to sleep (same is true of iPad, or any iOS device). This is a feature designed by Apple....and would cause the behavior you are describing. I have seen it cause some constrrnation with an iphone user of mine when we started locking down our network.
Second thought is that there is a list of ActiveSync implementation issues as long as my arm (not kidding), which could cause any number of issues (granted, it only focuses on 29007pm & 290102, but still....sheesh! - url is below). This is probably one of the driving factors of why Microsoft recently bought Accompli....they were tired of everyone screwing up ActiveSync. http://support.microsoft.com/kb/2563324 http://blogs.microsoft.com/blog/2014/12/01/microsoft-acquires-acompli-provider-innovative-mobile-email-apps/ Not sure what else, but that's my first two guesses. Good luck and let us know what you find! Jonathan Sent from my Verizon Wireless 4G LTE smartphone -------- Original message -------- From: Robert Cato Date:12/23/2014 6:39 AM (GMT-05:00) To: exchange Subject: [Exchange] Ex2013 - iPhone Connectivity Issues We recently upgraded to Ex2013 (CU6) from Ex2007. The new environment includes Kemp hardware load balancers sitting in front of two physical servers that have both CAS and mailbox roles. There is a DAG, with databases split between the two servers. We have several reports of users not getting emails. The users will get a flood of emails after manually opening the mail app (even though they are configured for push) or sometimes they have to hard reboot the phone. I have seen it first hand on my phone. I tried turning off wifi, toggling airplane mode. Nothing worked until I rebooted the phone. For the most part messages get delivered to phones, but there are too many reports of the issue to ignore. Appreciate any insight on how to troubleshoot this issue.
