XFOR: Remote Chat Service Stops Unexpectedly When Operator Privileges Are Given to a User

ID: q216963

The information in this article applies to:

Microsoft Exchange Server, version 5.5 Service Packs 1, 2
Microsoft Commercial Internet System version 2.0

SYMPTOMS

If you create an auditorium channel on a Microsoft Exchange Chat Service computer, and then one or more users join the channel from a different server, the Chat Service on the second server may stop unexpectedly when you use the MODE +O command to give operator privileges to a user in the channel.

CAUSE

When operator privileges are given to a user in an auditorium channel, the Chat Service attempts to notify all users in the channel that the change has taken place. This problem occurs because the Chat Service does not properly notify remote users.

RESOLUTION

To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For additional information, please see the following article in the Microsoft Knowledge Base:
