I use Outlook 2007 via POP3 for Hotmail (Windows XP, Service Pack 2). Since the last 15 days, on starting outlook 2007, I get an Internet Security Warning “The server you are connected to is using a security certificate that cannot be verified. The target principal name is incorrect. Do you want to continue using this server ? Y/N” On Microsoft Support http://support.microsoft.com/kb/958977/en-us, mentions that root of the problem is that the target server is Small Business Server 2008. Has Hotmail recently moved some email accounts to Small Business Server 2008 ? And is the problem that I’m facing due to Hotmail’s recent change or this is some malicious ratware / virus posing as Hotmail domain name. I use Quick Heal Total Security antivirus and they have confirmed that there is no virus. Also my computer clock setting is correct. Please help with the solution.
