a hard time connecting to an Exchange 2010 mailbox using an Outlook 2003 client? Here’s the deal. So as most of you already know Exchange 2010 introduces a new client access service named RPC Client Access. This service lives on the outlook 2003 exchange 2010 compatibility Client Access Server (CAS) and allows MAPI clients (Outlook) to connect to a CAS server

You can check this setting using the following command: Get-RpcClientAccess | fl This is not an issue if you use Outlook 2007 or Outlook 2010 since these Outlook versions have RPC encryption enabled by default, when you create a new Outlook profile, see below: But guess what? Yes the old Outlook 2003 exchange 2010 outlook 2016 version behaves differently. You see, when you create a new Outlook 2003 profile, RPC encryption is disabled by default in this client version. This means that if you migrate an Exchange 2003 or 2007 mailbox to Exchange 2010, or try to create a brand new Outlook 2003 profile against an Exchange 2010 mailbox, you won’t be able to connect to the mailbox.

Exchange TeamApril 23, 201014 Share 0 0 There are several scenarios for consideration when deploying Exchange Server 2010 in an environment where Outlook 2003 is used. Most of these scenarios have been documented prior to the product release and some applied to previous versions. However, in a review of support cases, we've found that they have not been used prior to contacting Microsoft. This post introduces some of the scenarios and the articles that will resolve these issues. If you're planning a deployment of Exchange 2010, understanding client configuration and the requirements and capabilities of your organization are of importance to the user experience. Primarily field http://www.msexchange.org/blogs/walther/news/exchange-2010-and-outlook-2003-clients-connection-issues-460.html office environments or environments where users are not joined to the domain, profile distribution, or the ability or inability to enforce policies or distribute the solutions will dictate how you address the issue. Encryption This is a top support issue for Outlook 2003 access to Exchange 2010. Note: In Exchange 2010 Service Pack 1, the RPC encryption requirement has been disabled by default. Any new Client Access Servers (CAS) deployed in the https://blogs.technet.microsoft.com/exchange/2010/04/23/common-client-access-considerations-for-outlook-2003-and-exchange-2010/ organization will not require RPC encryption. However, any CAS servers deployed prior to SP1, or upgraded to Service Pack 1, will retain the existing RPC encryption requirement setting. Also bear in mind disabling the RPC encryption requirement on a CAS server won't lower the security between Outlook 2010/2007 and any CAS server as RPC communication for these Outlook versions will remain encrypted. Exchange 2010 introduces additional "out of the box" security for client communications with the Exchange Server — encryption between the client and the server is enabled, by Default. This is RC4 encryption - where the client negotiates the encryption level based on the client operating system's capabilities, up to 128-bit encryption. This is documented in the following topic in Understanding RPC Client Access Prior to Outlook 2007, encryption was not enabled on the client side, by default. However, if profiles for Outlook 2007 exist where encryption is disabled, or if Outlook 2003 profiles created with default settings are used with Exchange 2010, the connection will fail when Outlook attempts to connect to an Exchange Server 2010 mailbox.
