This is a an application that uses the MAPISendMail function to send mail. When Outlook Express is configured as the default e-mail client, both the 32-bit and 64-bit version of my program opens an e-mail message when the function is called, which is the default behavior.
When Office Outlook is configured to be the default e-mail client, the 32-bit version of my program works fine and behaves accordinly, but when the 64-bit version runs it brings the New Connection Wizard. In other words, the 64-bit version the MAPISendMail is not finding the configured Office Outlook account to send the mail.
Any ideas on why this is happening or a workaround?
