There is no forum for Exchange 5.5, as this product is no longer supported by Microsoft. Additionally there is no Exchange 2003 forum as these forums are only for current products. You might try a newsgroup however: http://www.microsoft.com/communities/newsgroups/en-us/default.aspx?dg=microsoft.public.exchange.setup&cat=en_US_a7f336ef-ee56-4b9c-9cbd-1dbffae40b91&lang=en&cr=US But this may help anyway: http://www.msexchange.org/tutorials/Migrating_Exchange_5_5_to_2003.html
