OT: MAPI -- Why it sometimes work, and sometimes doesn't ?

Rick, I actually have the setup so my client can use SMTP, CDO, or MAPI. My SMTP and CDO routines work fine, but some want everything to go through MAPI ( Outlook ) so they can see Sent emails and all responses in one place. SO ... that is why the question was specific to MAPI. It works great here and on many of my clients, but one person is having "issues" ... and perhaps others. There is one other BIG advantage to MAPI. While SMTP and CDO are set system wide, MAPI allows them to have emails go out from separate accounts ... ie. sales, service, info, etc. Here is my MAPI code. As I said, it works great on many setups: [code=fw:7fqe7ohl][/code:7fqe7ohl] Tim
