To register the Outlook Live server with the server running Office Communications Server, you need to add a trusted server entry for each Outlook Live server or Exchange Client Access server. Microsoft Office Communications Server 2007 R2 Web Trust Tool simplifies the trust provisioning process.

To Download the Web Trust Tool

  1. To download the Web Trust Tool, go to http://go.microsoft.com/fwlink/?LinkId=135131 and then click Download.

  2. In the File Download dialog box, click Saveto save the file to a server running Office Communications Server 2007 R2.

The Web Trust Tool is a command-line tool (OCSWebIMTrust.exe) that you can use anytime that you need to establish trust for an Outlook Live server, or to remove a trusted server entry for a trusted Outlook Live server. It works by searching Active Directory and locating all instances of Outlook Live server or Exchange Client Access server. It then adds each server found to a list of trusted server entries.

By default, the tool searches through all trusted forests, but you can specify one or more forests and effectively bypass a forest that you do not want to scan. You need to run the tool every time you add or delete an Outlook Live server or Client Access server from the forest.

Command Line Arguments

You can run the Web Trust Tool (OCSWebIMTrust.exe) from a command line of a trusted server running Office Communications Server 2007 R2. The syntax for the command-line tool is as follows:

Copy Code 
OcsWebIMTrust.exe [/add [/forest:<forest1>[,<forest>]*]
|/deleteall |/clean |/list /?]

To provision trust by using the Web Trust Tool

  1. Log on to the server as a member of the RTCUniversalServerAdminsgroup or with an account with equivalent privileges. This group must also have privileges to each Active Directory container that includes Outlook Live server or Exchange Client Access server, which gives members of the group, read permission on the Outlook Live objects. The server must have the Office Communications Server administrative tools installed.

  2. Using the command-line arguments listed in table 1, at the command prompt, enter the appropriate command-line options and arguments.

Example

To enable Outlook Live servers from all trusted forests, enter the following command string:

In situations where some Outlook Live servers have been retired, you can use the following command string to remove trusted server entries for Outlook Live servers that no longer exist in the trusted forest:

Note:
This command will also add any new servers that have been added to the forest.
Copy Code 
OCSWebIMTrust.exe /clean

To list fully qualified domain names (FQDN’s) for all Outlook Live servers that are in the Office Communications Server trusted list, enter the following command string:
Copy Code 
OCSWebIMTrust.exe /list
