Messenger Service now requiring HTTPS (and error code 80072efd)
In the last fortnight, Microsoft restricted previously revived or third-party Messenger clients to use HTTP access. Yesterday, they improved security by requiring TLS instead of SSL. Today, they’ve gone a step further and now require HTTPS, therefore making Messenger conversations encrypted to the Microsoft server. Presently, the only non-modified desktop Messenger client to support this is Windows Live Messenger 2012.
For versions of Windows Live Messenger 2011, 2009 or 2008, you will get error code 80072efd and you will need to re-revive with Messenger Reviver 2.4.0 for Messenger to work. For all other clients (Pidgin, Adium, other libpurple clients), where the option allows, you can continue to sign in by changing the Messenger server from messenger.hotmail.com to msn.messengergeek.com.
If you wish to still use the major Windows Messenger 4 or 5 versions, Messenger Reviver 2.4.0 will patch those too. In Reviver, choose the Advanced button and then Patch Messenger option to revive these older Windows Messenger clients.
At the moment, Messenger:mac will not be working. Future versions of Messenger Reviver 2:mac should be able to fix it.
