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.

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 with the body: unsubscribe exchangelist
