[SOLVED] How to send an email with an attachment via outlook programmatically?

How to send an email with an attachment via outlook programmatically?

My app starts an outlook and send an email with an attachment. My new pc has a different version of outlook, The version is 1.2023.1018.300 (Production). Client Version is 20231013005.12 .

My app get an error with the new outlook. The error message is "Invalid class string".

The error is from starting an outlook process by using ole.

     ``` Outlook:=CreateOleObject('Outlook.Application') ;```

I guess the new outlook has a different name.

I tried using ShellExecute as well. This way launches outlook without error, but it doesn't have an attachment in the email.

``` ShellExecute(handle, "open", em_mail, NULL, NULL, SW_SHOWNORMAL);```

The em_mail is 'mailto:' & recipient_email_address & '?subject=' & subject & '&body=' & body & '&attachment=' & attachment_path;

Thanks for your help.

Solution

The new Outlook (Monarch) does not have the same COM API as the desktop Outlook. It does not have any API besides Web addins (JS).
