MSN Messenger Access To Be Restricted

linuxwrangler writes "According to Infoworld, Microsoft has announced that as of October 15 some third-party software and older versions of MSN Messenger will no longer be able to log in to their Instant Messaging service. Microsoft cited 'security issues', but declined to offer specifics. The company sent an email alert to Messenger users, but users reported thinking the message was a hoax or virus after receiving over a dozen copies of the email."
