To answer your question, no I didn't create an additional profile as I already had one for testing - I used that. If you find the MS instructions confusing then there's a set of instructions
here or a free utility
here that can create MAPI profiles. It should be OK but you use that at your own risk, I can't be responsible if your PC blows up or it eats your email.

Make sure you have a backup first.
