Hello all, I'm having a problem configuring an Outlook 2007 client behind a firewall to use RPC over HTTPs. I may struggle to explain the scenario clearly, so bare with me...
Environment: Exchange 2003 FE Server 2 Exchange 2003 BE Servers Windows 2003 AD Outlook 2007 I have a server that runs a particular application that needs to use Outlook for MAPI connectivity with Exchange. This server sits behind a firewall as it is governed by PCI although the server is a member of the same domain as Exchange. I'm attempting to setup an Outlook profile for the service account the application runs under. I'm unable to resolve the mailbox name during the profile setup when logged in as that service account. The service account has Domain User privileges and is an Administrator on the server. Here's the weird part. I can have the System Administrator of this particular application, who is also an Adminstrator on the server, log into the server and successfully create the Outlook profile for the Service Account mailbox. We verified connectivity by launching Outlook, authenticating as the service account, and verified we were connected via HTTPs by looking at the Outlook connection status from the system tray icon. I've also tested RPC over HTTPs successfully using an Outlook 2007 client that is not behind a Firewall. It seems like the issue is somehow related to the service account but I'm not sure what permissions it would be lacking that would cause this behavior. - Sean
