I moved my server from my data center to our in house server room last week. In the process, the server's internal IP address changed from 192.168.0.20 to 192.168.1.20. Our external IP remained the same, we just changed ip mappings on our router to route to the new IP.
Since then we've been working fine except for:
1) External Users in Outlook 2003-2010 - keep getting prompted for user/pass. After a minute there is an error dialog with the message: There is a problem with the proxy server's security certificate. The name on the security certificate is invalid or does not match the name of the target site mail.____.com. Outlook is unable to connect to the proxy server. (Error Code 0)
2) iOS users and Android users unable to get email. There is no descriptive error, but I'm sure its related to the issue above.
I'm running Exchange 2003 on Windows Server 2003 (Standard).
I have verified that my certificate (self assigned) has not expired.
Any help would be appreciated, I've got the President and Owner without email and they aren't happy to say the least.
Thanks in advance.
