Hi, I have installed windows 7 32 bit with MS Outlook 2003. I have a VB6 app which uses the MAPI controls 6 to send emails. I am currently getting a 48389 error message on the ResolveName property with no error description. I still get the MS Outlook prompt to allow access. I assume there is now a security issue with Windows 7 and allowing external applications to access the Outlook address Book? This functionality works fine or previous OS's. Any help here would be greatly appreciated, Thanks.
