What if the "support" email address was added to Outlook as an IMAP account in addition to the agent's regular address? What would happen if the agent simply did a drag/drop of the email into the inbox for the "support" mailbox. If it's IMAP, then it should be copied up to the server and then SmarterTrack would POP into the mailbox to get that email.
Would it matter what the TO: address is for that email if things were setup that way?
