RE: ActiveSync + Throttling + IOS

Re: ActiveSync + Throttling + IOS
First, I found that Exchange will allow you to block only as far as the model - so block all iphone 5s. Um, no. then I found this: http://www.flamingkeys.com/2011/10/how-to-block-iphone-4s-from-connecting-to-exchange-2010/ and this: http://social.technet.microsoft.com/Forums/uk/exchangesvrmobility/thread/7271bbb4-2946-45e9-8e94-9926ccf579bd which I *thought* would do it, but I'm having a hard time making it work. I'm trying to block iOS6.1 10B141 but I'm not sure that's exactly right either. We have over 50 devices on that list, so I'm sure I won't be able to block them anyway.

Honestly bud, this thread outlines as it is. Keep logparser on hand. During the period where I was seeing it, I used a batched job to keep an eye on the growth and email me over and above the normal nms we have with thresholds defined. This way if the growth was increasing I could react quickly.

RE: ActiveSync + Throttling + IOS
Michael, We are currently tracking both of the issues you have mentioned with apple via CSS now. My issue is about to be placed on the list if I have anything to say about it. I have some special access but the best pressure I could apply to apple would be public awareness and calls to them from their customers. Most customers who see the issue will modify their throttling policy and move on not knowing that they are now allowing IOS phones to blow up their CAS servers. From: Michael B.

RE: ActiveSync + Throttling + IOS
Andy, you are not alone. The issue you are talking about is on the radar. From: Leedy, Andy [mailto:ale...@butlerschein.com] Sent: Thursday, February 7, 2013 1:52 PM To: MS-Exchange Admin Issues Subject: RE: ActiveSync + Throttling + IOS We had a very excessive Exchange log generation issue. I found that two iphones that were recently updated to IOS 6.1 were stuck in loop trying to sync their calendars. These two phones alone were causing 3 GB of log growth per hour. The way I resolved it was by disabling activsysnc on their mailbox, removed the phone partnership, deleted the active sync account on the phone, rebooting the phone, re-enabled active on the mailbox and re-added the exchange activesync account on the phone. I opened a ticket with Microsoft PSS, but they said they had no way to prevent future occurrences so they just refunded my ticket. No hotfixes or patches. It's too bad. It seems like an easy way to attack a 2010 Exchange server would be to pound activesysnc until the log drive was full and the server crashed.

RE: ActiveSync + Throttling + IOS
...and I just got more info. After the recent release of iOS 6.1 Update, ... are reporting an issue around how iOS is communicating with Exchange server when the user responds to a meeting invite or update using iOS device. The behavior is such that iOS gets an error back from Exchange when trying to issue the meeting response command and simply retries the command over and over again. The recommendations are: [1] call Apple, [2] Don't roll out the new iOS update, [3] delete the device association to prevent it from getting worse. CSS is fully engaged.
