Via BGR, it looks like iOS 6.0.1 is being tested now and would address the Outlook / iOS 6 bug that caused meetings to be deleted.
In addition, the new software will improve Wi-Fi support, fix cellular
data not working in some cases, add a consolidated cellular data
switch for iTunes Match, fix a bug that allowed access to Passbook
pass details from the lock screen, and also finally fix the bug that
caused Exchange meetings to be unexpectedly cancelled for the entire
calendar invite group.
