Hi Kate,

We've had one other report of Adagio emailing using MAPI and Outlook Express and some email addresses working (such as the business partner like yourself) but others not working. But never did get the final resolution - they chose to email to a known working address and re-direct from there...

Does Direct method work for the same email addresses that fail under MAPI?
Could there be some patterns as to email addresses that exist in the Outlook Express 'address book' or not? Maybe why yours works? Just a guess and a hunch.
