Hello, The sbs 2008 exchange setup allows me to send and receive smtp emails via Outlook on the domain or using the Outlook Web Access facility. The problem lies with external IMAP connections to the exchange server. I can get Outlook whilst on the move to connect and pull contents of the email folders but I am unable to send via IMAP. The same applies to my handheld device, Incoming OK, Outgoing not happening. All relevant ports on the firewall are open and forwarding to the server eg, 25,143,587,993.
Been through the exchange management consol and within IMAP4 properties set the x509 certificate to remote.domain.co.uk and use a secure logon (TLS connection)
In outlook new account settings, Incoming is set to domain.co.uk and outgoing to remote.domain.co.uk. For outgoing authentication is set to same as incoming.
The Exchange IMAP service is running, I have tried several combinations of ports on the Clients using Outlook 2010, Entourage 2008 on a Mac and my HTC handheld. All connect to the inbox and update emails as they arrive but nothing goes out. Error message from Outlook is:
Task 'email@example.com - Sending' reported error (0x80042109) : 'Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).
Any ideas? Many Thanks.
