Mail Send from Windows Application

  • Hello everybody,

    I try to send a mail from an Windows application.
    The e-mail address given by the application is not accepted.
    The subject and the possible file attachment is accepted in the generated mail.
    What is wrong?

    Kopano Core: 8.4.0-22
    DeskApp: 1.2.67

    Best regards

    Hi vwrcs,

    To help understand this problem better, could you clarify with e.g. screenshots or steps?

  • Hi marty,

    our program uses the call via the registry entry HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Kopano DeskApp\shell\open\command

    --create --mailto=mailto:?subject=test?attach=... is passed as parameter.
    The email address is missing, So an error from our program.

    Is it possible to log the calls to the deskappmapi.dll ?

  • Hi marty,
    I think the problem is nevertheless the kopanomapi.dll. VS/Deskapp MAPI/main.cpp

    Line 103

     * TODO: Add recipients if needed
    	sCommand += sDeskappCommand; // path to deskapp.exe
    	sCommand += TEXT(" --create");
    	if (lpMessage->nFileCount > 0) {
    		sCommand += TEXT(" --mailto=mailto:?attach=");
    		sCommand += sAttachments;

    Only the attachment is accepted.

  • Hi marty,

    I have adapted the kopanomapi.dll. Now the recipients, the subject and the mail text are accepted.
    If necessary, I can make the changes available.

    Hi vwrcs,

    sorry didn’t see your post until now…
    Would be ultimately awesome if you could share your efforts.
