OUTLOOK 2007 SEND AS PERMISSIONS

I have a program that uses a CALL to OUTLOOK to send documents from itself to the user's OUTLOOK  to automate the sending process. When it does this a OUTLOOK popup window appears stating that a send as request is being made and you have to click on the allow button to complete the sending process. Is there a way to somehow disable the popup alert or allow to "send as" for the application?WHen the users are sending 100 documents they have to click the allow button 100 times.  We have Exchange Server 2007 in house for the back end and are using the full outlook, not express.
