I'm running SBS 2011 w/ exchange 2010. everything was working fine, i decide to change my ISP provider. Now i can receive the emails in exchange but when sending the emails nothing get thru. I have no errors, emails in the outlook ( configure with exchange account only and configure in the server with pop3 connector) are mark as send but nothing is delivered. Where i can change the outgoing (smtp ) in the pop 3 connector , maybe trying a diferent port.
Can someone give me some light in this issue.
