SYMPTOMS
Consider the following scenario. An archiving server is connected to a director in Microsoft Office Live Communication Server 2005 Enterprise Edition. The director is used by the Enterprise Edition pool.

In this scenario, federated users cannot send instant messages to internal users.



CAUSE
This problem occurs because of how the access proxies are configured. For example, the route that is followed by an invitation differs from the route that is followed by a message. When the two kinds of routes are set the same, the archiving algorithm may break and the archiving server may not work.



WORKAROUND
To work around this problem, do not enable the archiving service on the Enterprise Edition pool.

Note The Enterprise Edition pool uses a director. However, the Standard Edition pool does not use a director.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
