Perfect :( we have users connecting with their home devices and we have zero control. We are having a hard time getting policies approved and in place. On Thu, Feb 7, 2013 at 5:19 PM, Michael B.

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.

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. If there's a Microsoft Exchange Team inside guy on this forum that wants to explore this further please feel free to contact me. I think it's a security issue that should be investigated. -Andy From: Michael B. Smith [mailto:mich...@smithcons.com] Sent: Thursday, February 7, 2013 3:58 PM To: MS-Exchange Admin Issues Subject: RE: ActiveSync + Throttling + IOS Don't you have more inside access than we do? :) A couple of things are starting to percolate up with this latest iOS update - excessive log generation and throttling hits are being discussed on several forums. I haven't heard of any conclusions out of CSS yet, and none of my customers have reported any issues so I don't personally have a call open. From: KevinM [mailto:kev...@wlkmmas.org] Sent: Thursday, February 7, 2013 3:12 PM To: MS-Exchange Admin Issues Subject: ActiveSync + Throttling + IOS I am tracking an issue for a number of customers where apple IOS devices are causing the %time in AD throttling policy to fire due to devices performing full GAL lookups for each key press. My feeling is that this is an IOS design flaw that should be fixed. Windows Phone searches local device contacts then presents an option to attach to GAL; A much less expensive task for an Exchange server. Too an end user the symptoms are delayed send and receive. Most noticeable are messages waiting to be sent on the device until the throttling blocking is removed. The issue can be seen when you correlate IIS logs throttling errors with Activesync Mailbox logs and you look for <query> RequestHeader : POST /Microsoft-Server-ActiveSync/default.eas?User=xxxxxxxxxxxxxxxxx&DeviceType=iPhone&Cmd=Search HTTP/1.1 RequestBody : <?xml version="1.0" encoding="utf-8" ?> <Search xmlns="Search:"> <Store> <Name bytes="3"/> <Query>r</Query> I am wondering if anyone else is running into this issue? --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com<mailto:listmana...@lyris.sunbeltsoftware.com> with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com<mailto:listmana...@lyris.sunbeltsoftware.com> with the body: unsubscribe exchangelist ********************************************************************** CONFIDENTIALITY NOTICE - The information transmitted in this message is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.
