In process of migrating Win 2003 SBS to a Win 2008 SBS Premium server.
All Outlook clients including Outlook 2003 and 2007, Blackberry services, Iphone, Entourage 2004 and 2008 used to connect to the old Exchange 2003 server ok.
Now they can all connect to the Exchange 2007 server except for the Entourage Clients and it's doing my head in.
The Entourage users can all log on using outlook web services in Safari via https://mail.%domain%.com/exchange
as a workaround but need to be able to use Entourage.
THe Entourage clients start up with the warning
":Unable to establish a secure connection to mail.%domain%.com because the server name or IP address does not match the name or IP address on the server's certificate."
WHen i apply the exchange account settings i get the following error"
"Entourage cannot connect to the Exchange server.
Explanation " Verify that your Exchange aaount detail settings are correct" Error -18597.
Actual domain name above has been amended to %domain% for privacy.
