I agree that there seems to be a lack of joined up thinking here. If it is using IPv6 addresses to access a login (as it clearly is) then it is barmy that CA blocks them.
We found we were having a lot of hacking attempts from particular countries so in an attempt to improve security set up CA last week to block attempts from such countries.
So now logins to Exchange via IPv6 are being blocked even though the IP6 addresses are clearly coming from a country that should not be blocked.
