I have had a most unproductive day trying to work out why after four years my outlook 2007 has stopped sending messages. Not just my machine either, the other two have exactly the same problem. Have checked all the usual suspects (put in every port listed and run tests ect.) and even resorted to phoning Orange for assistance as I think the problem is at their end. They demanded fifty Euro before allowing us to talk to a technician! Being a skinflint (and truly believing that the tech guys at Orange are still using Minitel) I wondered if anybody had come across this problem and managed to resolve it.
