@ZenInternetHelp After waiting in a queue for 1 hour 20 minutes, it turns out there are still issues. The ticket doesn't list it but the exchange in Norwich is down.
@ZenInternetHelp It did not work. It went down around 7:30am and won't come back. Clearly I'm not alone as I'm 30th in the support queue and I've been in for over 35 minutes
