Blocking iOS 6.1 Devices on Exchange 2010
This is more informative, the last few hours we started experenceing issues with Apple iOS 6.1, essentially malformed meetings on a device cause the device to get into a sync loop which causes excessive transaction log growth on the Exchange mailbox servers which will cause Exchange performance issues and potentially transaction log drives to run out of disk space.
Exchange has a limited ability in blocking options when using the internal blocking features users are presented with "Your password may be incorrect", however this solution provides a simple "The server refused connection" as an alternative, this was added to our previous /microsoft-server-activesync irule.
if {[HTTP::header "User-Agent"] matches_regex {^Apple.*1002.*}} {
reject
}
