A bug in messaging service Hotmail temporarily stopped people from a variety of countries from using their accounts in a secure HTTPS configuration.
On Friday afternoon, Microsoft said that Hotmail users trying to turn on HTTPs for the first time in a variety of countries had been prevented from doing so, due to a bug. The bug was resolved late on Friday, Microsoft said.
On Friday morning the Electronic Frontier Foundation said that the ability for users to turn on the always-use-HTTPS option in Hotmail was not working for users in Bahrain, Morocco, Algeria, Syria, Sudan, Iran, Lebanon, Jordan and a host of other countries.
People attempting to connect were given the message "your Windows Live ID can't use HTTPS automatically because this feature is not available for your account type".
"We do not intentionally limit support by region or geography and this issue was not restricted to any specific region of the world. We apologise for any inconvenience to our customers that this may have caused," a Microsoft spokesperson told The Register on Friday afternoon.
Microsoft first brought default HTTPS encryption to Hotmail in November.
