Yesterday, I blogged that users in Iran, all Arab countries, Burma, Nigeria, and the Central Asian nations had been blocked from turning on HTTPS encryption within Hotmail. This was true.
“We do not intentionally limit support by region or geography and this issue was not restricted to any specific region of the world. We apologize for any inconvenience to our customers that this may have caused.”
Having just tested this myself–by setting my country of residence on Hotmail to Syria and enabling HTTPS–I can state with certainty that the problem has been fixed.
