A channel's Security tab allows you to grant access
rights to a registered channel by identifying an individual or
group as a channel User. An authenticated channel
User can then be allowed or denied access to the
channel.
To limit access to a registered channel only to those identified
as User:
On the Start menu, point to
Programs, point to Microsoft Exchange, and then click
System Manager.
Navigate to the
Channels folder for the chat community where you want to
restrict channel access.

Channels
Click the Channels folder.
In the Details pane, right-click the channel to be restricted,
and then click Properties, or create a registered channel.
On the channel's Security tab, click Add.
From the list of users in your domain or trusted domains,
select the name of the individual or group you wish to identify as
a channel user, and then click Add Name.
On the Security tab, in the Permissions box,
select the Allow check box associated with User, and
then Click Apply.
