When I open Outlook through a "mailto" link, the New Message window comes up but the main Outlook window does not. That's okay except for the fact that when the user hits "Send" the message does not get delivered immediately. It stays in Outbox until the user opens Outlook to check their email, which could very well not happen until the next day!
We find this behavior confusing because we have a program that generates this kind of emails regularly (to send .PDF files to customers) and my users expect the messages to be sent immediately.
We're looking for a way to force Outlook to send the message even if the main window is offline, or alternatively force "mailto" links to open Outlook in full mode.
