SYMPTOMS
When you use Microsoft Office Live Communications Server to host Windows Messenger sessions, and you use Windows Messenger to send an instant message to another user, you may receive the following error message:

The following message could not be delivered to all recipients.



CAUSE
This problem typically occurs when the default routing application setting (routing.am) has been disabled or removed from the Live Communication Server Applications module.



RESOLUTION
To send Windows Messenger INVITE requests to another user, you must make sure that the routing application setting (routing.am) is enabled. To do so, follow these steps:
 * 1) Click Start, point to Programs, click Administrative Tools, and then click Live Communications Server.
 * 2) In the Live Communications Server console, expand Servers, expand  , right-click Applications, and then click Properties.
 * 3) In the Applications Properties dialog box, make sure that routing.am is listed under Available Applications, and then make sure that both the Enabled and the Critical check boxes are selected.
 * 4) If routing.am is not listed under Available Applications, click ADD.
 * 5) In the Add Script-Only Application dialog box, click Browse, and then specify the path of the routing.am script. In the Application name box, type Routing Application Setting - Default . In the URI name box, type: http://www.microsoft.com/RTC/DefaultRouting, and then click OK.

Note By default, the script path is :\Program Files\Microsoft LC\Server\routing.am.
 * 1) Make sure that both the Enabled and the Critical check boxes are selected, and then click OK.



STATUS
This behavior is by design.



MORE INFORMATION
Uniform Resource Identifiers (URI) are typically used as unique identifiers. In Live Communication Server, the URI is a string that shows both that the routing script was written by Microsoft and the purpose of the routing script. It is not an actual destination. The URI can be modified, but any change must also be reflected in the script.
