Every time that I open Outlook 2007 to connect to exchange server 2007 I get this error. atlmsx01.drtango.int (Server name: atlmsx01 Domain: drtango.int) Information you exchange with this site cannot be viewed or changed by others. However, there is a problem with the site's security certificate. X The name on the security certificate is invalid or does not match the name of the site. I know that the error is because outlook is connecting to exchange using the internal domain name and it doesn't match the certificate that is using the external URL. What is the easiest way to fix this? Thanks

Is there a graphical way to do this?I dont really want to messup nothing on the server.Thanks

Nop, no GUI way in EMC but you can save all current settings with Get cmdlet instead of Set like below for backup... Get-ClientAccessServer -IdentityCAS_Server_Name| FL > ClientAccessServer.txt Get-WebServicesVirtualDirectory -Identity "CAS_Server_Name\EWS (Default Web Site)"| FL > WebServicesVD.txt Get-OABVirtualDirectory -Identity "CAS_Server_name\oab (Default Web Site)"| FL > OABVD.txt Get-UMVirtualDirectory -Identity "CAS_Server_Name\unifiedmessaging (Default Web Site)"| FL > UMVDtxtAmit Tank | MVP Exchange Server | MCITP: EMA | MCSA: M | http://ExchangeShare.WordPress.com
