Hi Aaron,

 

 

This is a newly discovered issue with iOS 6.1, more details (http://www.windowsitpro.com/blog/tony-redmonds-exchange-unwashed-50/exchange-server/apple-ios-61-upgrade-excessive-transaction-log-growth-145223)

 

 

Subsequently we have re-opened our environment to iOS 6.1 devices but disable the Meeting Response ActiveSync command from 6.1 devices as this appears to be the cause. The code below puts the effected devices calendar into Ready Only mode until Apple release an update.

 

 if {[HTTP::header "User-Agent"] matches_regex {^Apple.*1002.*} } {
 if { [HTTP::uri] contains "Cmd=MeetingResponse" } { 
reject 
}
 }

Please use this at your own risk.

 

 

Dan.
