Recently lost ability to log on to my mobile email, which is through att.net. Worked perfectly for years - Still on my Samsung 4G. My att site email works.... my Outlook Express works.... cannot log into it using my mobile. I have tried deleating my mobile email anf reinstalling it, but now it won't allow me to do that. Error msg says: "Cannot Safely connect to server / Cannot Validate Certificate Signature." What am I missing here?
