Hello,
I had an Windows Server 2003/Exchange 2003 Server with a domain1.com as AD and mail domain.
The customer company changed the name, i added a new mail domain in Exchange sevrer (domain2.com)
I upgraded to Windows 2008/Exchange 2010.
I used a Self-Signed certificate for this installation, recently, i ordered and installed a wildcard comodo certificate *.domain2.com as this is the internet domain used by the custromer, i affected this certificate to IIS and SMTP services.
In the webmail, i did not get the security error any more. BUT, after few hours, the Outlook users called to tell us that they receive a security alerts on the Outlook. After a few searchs, i think the problem is that there is some flow exchanged between Outlook, AD and Exchange using the internal domain (domain1.com).
I did a rollback to the Self-signed certificate until i find a solution.
Do you have any idea about that issue? Any suggestion?
Regards.
