Setting up email addresses
Exchange Server hosted in an application service provider (ASP) environment is similar to a corporate Exchange deployment. Smart IT departments can think of themselves as ASPs, with their own organization as their customer. This article is the second in a series about the Exchange 2000 Server lessons you can learn from ASPs.
In "Exchange 2000 Hosting: The ASP Model, Part 1," November 2001, I described the front-end/back-end architecture that ASPs use for Exchange and told you that ASPs typically establish one Active Directory (AD) forest with a separate organizational unit (OU) for each company they host. Likewise, you might set up one AD forest, with a separate OU for each of your corporate divisions. I also showed you how to define a user principal name (UPN) suffix for a division—Division A—and associate it with the logon names of the users in that division. (For an explanation of how to create a UPN suffix as an OU property, see the sidebar "Creating a UPN Suffix as an OU Property," page 12.) . . .

People from different companies can still see groups from other companies unless the LDAP query built the way so there's no group at all.
Is there any way to manually edit query for an address list?
The other problem is when I specify properties for user object in LDAP query all groups keep disappearing from address list and vice versa.
