I need a macro to attach a file when the user clicks on send. There are criteria involved: I need to check the recipient to see if an email has already been sent to that recipient(s) on that day, and if so, send the email without the attachment. Also if the user is internal to the Exchange (2007) system then never attach the pdf file.
If there are several users and all are internal then don't attach. If only one is external then attach the file. Outlook is version 2003.
