So we have recently relocated to a new premises and it doing so have got a new static IP address at our new office. I have managed to sort everything excpet for remote exchange users being unable to connect. I have tried re-creating the email account of the remote users computer but still cant get a connection.
Any ideas?

having you tried using RPC over HTTP connect your users. It could be a firewall issue you are having. Also your other option is to get them to use OWA instead.

OWA works fine... Yeah the remote users are using RPC over HTTP...

No, incorrect, my problem is not resolved... My remote users still cant connect to exchange. OWA is not the method of using their emails that i had setup previous to our relocation. So i need to try and find out why i cannot get Outlook to connect  to the Exchange server.

Have you tried changing the ports on the firewall. What firewall rules have you applied?

I assume you changed the public DNS records to point to the new IP?

The ports on the firewall have not changed from their previous configuration...

You should only have to change public DNS and on SBS 2003 run the Configure E-mail and Internet Connection Wizard, and on SBS 2008/2011 run the fix my network wizard. No changes in the wizards should be necessary.

RobWill, im obviously not as retarded as i was starting to think. I was under the same impression as you. I have the SBS2011 so i ran the fix my network wizard and changed the DNS records to point to the new IP... I thought it all should have been sweet... But it just wont connect...

If it helps, i think it has something to do with the RPC over HTTP as i can connect to the exchange on my iphone and have been getting mail the entire time on my iphone.

OWA doesn't require a certificate, but rpc/http does.  No reason that would change with a move, but might be a clue as to why the difference.  I assume the new DNS pointer uses the same FQDN as before, so that it matches the certificate.

To test the certificate does RWA work to the point that you can log onto the server?  You can get to the RWA page without a cert but not pass through to the server or a PC.

Thanks for pointing me in the right direction. I was able to attain that it was a problem with the Certificate and that if i opened IE on the machine in question and clicked install certificate and installed it into the trusted root certificates folder, Outlook then had no trouble connecting to the Exchange server.
Thanks for your help RobWill...
