Mark,

OutlookExpress has a checkbox on the Send page - Send Messages Immediately. It's big brother should have the same thing. You also have to make sure that Outlook is set as the Simple MAPI client on the machine for it to work with the MAPI controls.

>I've developed an application on a Winnt machine, which automatically sends off an e-mail, with an attachment. This works fine on my Winnt machine, but when I come to run it on a Win98 machine, I get my e-mail popping up on screen stating that "This message has not been sent". If I click the send button, the e-mail fires off ok.
>I've compared the various options in Outlook on both machines, but can't find anything that looks like it will cure this problem. I've noticed that you can put (.T.) at the end of the objMessage.Send line, but this seems to be ignored as I can't even get it to bring up this box on my PC using the (.F.) option.
