Ok so I finally got the connectors working but the problem is I cannot send emails with Outlook to Exchange 2003??
The weird thing is I can log into EX2010 OWA and send an email to a 2003 mailbox user just fine. But whenever I setup my mailbox (which is on 2010) in outlook and try to email a 2003 user I instantly get:
There's a problem with the recipient's mailbox. Please try resending this message. If the problem continues, please contact your helpdesk.
I am using Outlook 2007... so why would this work in OWA but not a Outlook profile?
