MAPI Settings

Edit online

If you use Exchange Server 2013, use the MAPI Settings property page to verify that the user mailbox is online. You can also view and update the MAPI registry key that enables Data Protection for Exchange Server to connect to the Exchange Server.

Data Protection for Exchange Server automatically generates a default value for the registry key. Edit the registry key only if the default value is incorrect.

The values that you enter override the registry key that is in the HKEY_CURRENT_USER\Software\Microsoft\Windows NT\Current Version\Windows Messaging Subsystem directory. If you modify the registry incorrectly, the connection to the Exchange Server might fail.

You can use this property page only if you use Exchange Server 2013.
RpcHttpProxyMap_TSM
Change the registry key values to reflect the correct domain, endpoint, and Remote Procedure Call (RPC) authentication methods for your environment. By default, the format is:
Domain=Proxy Server,RpcHttpAuthenticationMethod,
RpcAuthenticationMethod,IgnoreSslCert
For example: 
companyname.local=https://exchange.companyname.com,ntlm,ntlm,false
where:
  • Domain value is the domain suffix of the personalized server ID, for example, companyname.local. Specify any domain or a substring of a domain, or the asterisk (*) and question mark (?) wildcard characters, for example, *.companyname.local.
  • Proxy Server value is the RPC proxy server that has the Client Access Server (CAS) role. Specify the fully qualified domain name (FQDN) of the RPC proxy server. Precede the FQDN by http:// for an HTTP connection, or https:// for an HTTPS connection. For example, https://exchange.companyname.com
  • RpcHttpAuthenticationMethod value is the method that is used to authenticate RPC-over-HTTP connections. Specify NTLM, Basic, Negotiate, or WinNT.
  • RpcAuthenticationMethod value is the method that is used to authenticate RPC-over-TCP connections. Specify NTLM, Negotiate, WinNT, Anonymous, or None.
  • IgnoreSslCert value indicates whether the Exchange Server validates SSL certificates. For the Exchange Server to ignore invalid certificates, specify False.
Domain
Change the domain name to reflect the correct domain if for example, you have multiple domains, or the default domain value is incorrect. To match all domains, enter the asterisk (*) wildcard character. When you change this domain value, the Domain value of the registry key automatically updates in the RpcHttpProxyMap_TSM field.
Use HTTPS authentication
Select this check box if RPC-over-HTTPS is enabled for the Exchange Server that is hosting the MAPI profile. Otherwise, clear this check box to ensure that HTTP authentication is used for RPC-over-HTTP connections. When you change this authentication value, the RpcAuthenticationMethod value of the registry key automatically updates in the RpcHttpProxyMap_TSM field.
