Certificate errors in Exchange 2010
Posted on 2014-07-18
We are using Exchange Server 2010 on Server 2008 R2. Recently upgraded some clients from Outlook 2003 to Outlook 2013.
Now they are getting certificate errors. It looks like Outlook is using the internal hostname of our Exchange server to connect. Our certificate only has the external hostname listed on it, and that's what I want Outlook to use to connect to the server both internally and externally.
If I go into "Connection Status" on Outlook, it shows the internal hostname in the "Server Name" field.
What are the EMS commands to check / set the various hostnames for Exchange Server so I can set them to all be the external hostname?
