Outlook Problem

YOU MUST FULLY UNDERSTAND THIS PROBLEM TO APPLY TO SORT IT. IF YOU WASTE MY TIME I WILL LEAVE NEGATIVE FEEDBACK. I'm moving my outlook to a new computer. However, even though I put in the exact same details into the new computer, it is refusing to set up certain accounts. It keep promoting me with the dialogue box that contains the email and the password. I've managed to set up some accounts fine but a number of others won't work. Hotmail seems fine as I have added two accounts. But it has only allowed one account for my own personal business email account. What can I do? This is the second time I have had this happen with different computers. And last time it happened I could not even solve the problem by moving to Mozilla's email program. I will pay £20 if you can solve it.
