Maybe I was a little hard on Kevin, he is now doing everything to help me out. I am not a computer professional and as far I know nothing was seriously wrong with that, fully checked by Microsoft Support. I did have a problem because I was running Outlook 64-bits and CM only work on 32-bits and I don't remember I was told. Kevin was very nice to supply me the 32-bits version and now sending single mails with no problems, bulk is still a problem, but maybe I don't understand it, getting old you see. I love CM, general very easy to use, that is why I am pressing on to get it to work 100%, I am sure Kevin will sort it our, just mailed him a back-up of my database, so he can play around. Will let you all be updated.
