I'm opening Outlook from a C# appplication using MAPI. Outlook
correctly created a new email window but the main application window
is disabled.
I noticed that the same thing happens when composing a new email with
attachment using the context menu (send attachment to email
recipient).

Is there a way to prevent the main window to disable itself (the same
way it happens when you compose a new email directly from inside
outlook?)
Thanks,
Andrea

Whatr is the relevant snppet of your code hat locks your app?
Are you calling IMAPISession.ShowForm() To display a message modelessly, use
IMAPIForm.DoVerb(EXCHIVERB_OPEN, ...).
Why are you opening a form using MAPI? Outlook Object Model would be a lot
easier.

Thanks for the reply.
I'm using MAPI because I need to connect to any email application.
I'm currently calling
int error = MAPISendMail(IntPtr.Zero, IntPtr.Zero, message,
MAPI_DIALOG, 0);

What call should I make? I don't want to send a message but just open
a new precompiled email message.

Do you have a snippet of code to do that?
Do you think it's better to use MAPI for all the applications and so
something different for Outlook?

Thanks.
Andrea

OK, that is Simple MAPI, I meant Extended MAPI (which only Outlook
supports).
There is nothing you can do in Simple MAPI...
You can test that the user has Outlook installed and use OOM instead:

set App = CreateObject("Outlook.Application")
set Msg = App.CreateItem(0)
Msg.Subject = "test subject"
Msg.Display
